Human Resource Management in Context Assignment

Human Resource Management in Context - Assignment Example 5). Key Developments in Human Resource Management – Hard and Soft Versions: The above-mentioned reason is enough to explain so many developments in Human Resource management in recent times. Human Resource Management can be differentiated between hard and soft versions. The followers of hard version treat their employees as one of the inputs in the business and try to utilize them in the best possible way to generate the most profit. For this, they try to reduce cost and try to focus on flexibility techniques. On the other hand, the followers of soft version of Human Resource Management believe employees to be the most precious asset of the organization and they apply different strategies to retain their employees and to make them happy (Armstrong, 2009, p. 5). It would be wrong to say as to which technique is the best. Companies choose a version on Human Resource Management depending upon its core values and company’s philosophies and design their HR strategy according ly. There are companies that apply a combination of both soft and hard versions of Human Resource Management. ... HR professionals would deal with the concerns of the employees as they arise from the employees’ side. However, the view of looking at an HR professional and the span of its roles and responsibilities have changed drastically over time. Now, HR professionals are seen in most organizations as business partners (Hunter, 2006, p. 6). The word â€Å"business† in Business Partners implies a strategic intervention. It refers to something that has to be implemented from the top i.e. designing the strategy. Besides, the term â€Å"partners† refers to working alongside, and at the same level with that of the top management (Charles and Fombrun, 1984 , p. 3). Now, HR professionals sit with the top management, help them, and advise them in designing a company’s strategy and that is where the role of strategic HRM comes into play (Charles and Fombrun, 1984 , p. 3). Once, a company’s strategy is designed then HR strategy is designed keeping in view companyâ€⠄¢s strategy. For example, if company’s business strategy is cost leadership so the culture in the organization would be such that would incentivise its employees on cost-cutting activities and the like (Kenton and Yarnall, 2009, p. 2). This is why, when today one talks about HR professionals, he talks about someone who is working hand in hand with the company in order to implement its strategy from top to bottom, and is thus playing a role of a Business Partner of that company. External Contexts of HRM: Today’s HR professional has to be aware about the key developments in the business or in business’ strategy. Moreover, he also has to be aware about the external context in which the business operates. By external context, we mean a company’s macro environment. This includes socio-cultural,

Women and Health Assignment Example | Topics and Well Written Essays - 1000 words

Women and Health - Assignment Example However, maybe due to the fact that they often compete with the opposite sex to be treated as equal, women of recent generations have neglected their well-being. Changed lifestyle has contributed a number of ailments to women that could affect their health during their childbearing years. There are prenatal screenings being offered to pregnant women to ensure the health and well-being of the child they are carrying. Also, couples are being offered screenings to know their so-called genetic compatibility or incompatibility to know the ratio of having a healthy and normal child. There would be instances that screenings would be disregarded by parents at some point and say that they would accept their child in whatever health condition they might be in whether at birth or at the course of their lives. What parents or future parents should consider is that, if they would not undergo screenings and their child would be suffering from a certain ailment, they as parents are disregarding the right of a child to grow up with a healthy body and be accepted in the society. One should accept that though as advanced and liberal the society might be there are still instances that physically and/or mentally challenged children suffer from discrimination almost their whole lifetime ( South-Paul, et al., 2004; Karpin & Savell, 2012). Another hindrance that might occur for prenatal screenings would be culture. There are aspects of the beliefs of ethnic groups and population where pregnancy or the child that is still in the womb is considered as sacred or should not be disturbed. This is an aspect which can be the topic of debates for years and decades, however, would still end up into nothingness. However, this should not be the case. There should be scholars from the medical field to address or enlighten these ethnic groups. Prenatal and even newborn screenings are not done to step on their traditions and cultures; these are done to ensure the future and well-being of the next generations and the generations to come after them.  Ã‚

Movie Review Example | Topics and Well Written Essays - 500 words

Movie Review Example For that reason, people need to come up with solutions for this crisis. In this essay, I shall try to review the solutions given in the documentary. First, we shall tackle water wastage. It is a miracle that people can take up to one hour in the shower. This is a clear wastage of water. People need to take shorter showers or better yet resort to baths, which would require the use of less water. The film also talks about the pollution of fresh water sources that prevent the use of water. An example of such pollution involves the use of the herbicide Atrazine. This herbicide is still used in the United States of America, despite being banned in countries such as Switzerland. The herbicide is so toxic that it decreases fertility in human males by reducing their sperm count and also causes prostrate and breast cancer. Therefore to solve this problem, the state needs to ban the use of all toxic chemicals that pollute our fresh water reservoirs. The next documentary that I shall review is called â€Å"The Intersection Between Justice and Sustainability: Voices and Views from South Phoenix†. This documentary mainly involves interviews carried out on the residents of South Phoenix. In this essay, I shall reflect on the actions taken by community leaders profiled in the film to address the 10 sustainability principles. In every city, social inequality, marginalization, and containment are some of common injustices experienced. One of these community leaders is Steve Brittle the founder of Don’t Waste Arizona. This is a non-profit environmental organization that was formed to protect, conserve, and preserve human and natural environment. One of the main problems that Phoenix faces comes from Innovative Waste Utilization. This company is located in a neighborhood mainly comprising of African American and Latino families and poses great hazard to these families. Furthermore, this waste facility planned to

Marketing Strategy of Procter and Gamble Term Paper - 1

Marketing Strategy of Procter and Gamble - Term Paper Example From this paper it is clear that other basic problems include but are not restricted to what appropriate marketing strategy to adopt—should Scope be positioned as a â€Å"better tasting pre-brushing dental rinse† against its previous recognitions as a â€Å"better tasting and breath freshener† manufacturing issue concerning how to produce product that will match the standardizations required by As the discussion stresses Canadian Health Protection Branch, The Canadian Dental Association and Saccharin/Cyclamate Sweeteners requirements; finding alternatives to funding the marketing of Scope since the product has so far received its highest finances in years, and that funding another line of product might be helpful to reduce cost competitively; recognizing the significance of spending more on advertising another line of product to shore up customers’ interest in Scope; and discovering the best approach as far as Procter and Gamble’s operations and purchasing are concerned. The cause of this important analysis of Procter and Gamble’s operations in Canada is based on the fact that other rivals in the same niche of health care product like Plax, Colgate, Listerine, Listermint and Cepacol which brandish their comparative quality of pre-brushing rinse has captured the market from Scope. This is because these other products offer consumers the opportunity to fi ght their plaque—â€Å"which is the soft, sticky film that coats teeth hours after brushing them†. The Canadian Mouthwash Market Shares below justifies the fact that Plax has made significant gain against Scope, having started with a mere 1% of the market share in 1988 to commanding an appreciable 10% of the same market in 1990.

Portfolio Essay Example | Topics and Well Written Essays - 1500 words

Portfolio - Essay Example 79). Managing and Developing Self Before joining the university and undertaking bioscience courses, I was not able to manage my schedules and so I had to depend on what had already been planned by teachers. However, my life in the university enabled me to understand how to manage myself, plan my time for different activities and manage my work in a professional way to ensure optimal use of financial, academic and time resources. The professional attribute of the university has assisted me in understanding how to manage my work, follow instructions closely with minimal supervision, plan my work schedule well in advance and ensure that all tasks are completed in a responsible and professional manner. For example, when conducting biological experiments, I ensure that I have read all procedures in advance before commencing the real practical work unlike in the past when I used to conduct experiments without reading all instructions. However, although I am able to manage my schedule well, the only problem that needs a lot of effort is in categorizing issues on the basis of priority. In many instances, I have been giving priority to relatively less difficult issues, thus ignoring higher priority but difficult issues. The consequences have been dire. For example, when choosing elective courses, I have been choosing less difficult courses at the expense of highly competitive ones, which are in most cases difficult (OHLSSON & BORG, 2010, p. 67). University education has given me various opportunities for self-development through constant learning and being a critical learner. I have come to understand that learning is not only about gaining knowledge about a specified subject but also to develop critical skills that would enable one to solve problems, make use of the available opportunity to develop the society, and be a continual learner through a number of avenues such as the Internet or part-time education programs. Further, university education has changed my notion from being a job seeker into being a job creator through a number of business courses that have enhanced my entrepreneurial skills (POSTMAN, 1995, p. 68). Communication Communication is an essential aspect of professional development and human interaction. Through good communication strategies, it is possible to develop positive relationship with people in the learning institution, places of work and the society in general. One of the important aspects of communication I have learnt from Staffordshire University is the use of information and communication in getting sufficient information within a short time and passing messages promptly and efficiently. Since I joined the university, I have learnt many aspects of using the Internet to get information that would have been cumbersome to search through conventional means such as physically looking for a specific topic among a variety of hard copy journals. I can easily surf the Internet and get information within a shot time. Further , online libraries have assisted me in learning different topics in biology within a short duration of time and use the

Entire Course (Managerial Economics) Essay Example for Free

Entire Course (Managerial Economics) Essay Firm Objectives. Why do some business firms pursue a triple-bottom-line outcome while others focus only on profit maximization? Please, use a real company example to illustrate your points Decision Making Under Uncertainty. To save on gasoline expenses, Edith and Mathew agreed to carpool together for traveling to and from work. Edith preferred to travel on I-20 highway as it was usually the fastest, taking 25 minutes in the absence of traffic delays. Mathew pointed out that traffic jams on the highway can lead to long delays making the trip 45 minutes. He preferred to travel along Shea Boulevard, which was longer (35 minutes), but rarely had traffic jams. Edith agreed that in case of traffic jams, Shea Boulevard was a reasonable alternative. Neither of them knows the state of the highway ahead of time. After driving to work on the I-20 highway for 1 month (20 workdays), they found the highway to be jammed 3 times. Assuming that this month is a good representation of all months ahead, should Edith and Mathew continue to use the highway for traveling to work? How would you conclusion change for the winter months, if bad weather makes it likely for traffic jams on the highway to increase to 6 days per month? How would your conclusion change if Mathew purchased a new smart-phone app that could show the status of the highway traffic prior to their drive each morning, thus reducing the probability of them getting into a jam down to only 1day per month (where on this day, the app showed no traffic jam, but a jam developed in the meantime as they were driving along the highway).

Roshima is researching universities where she could study for her MBA degree. She is considering 3 major attributes that she considers important in her choice: ranking, price, and location. The value she places on each attribute, however, differs according to whether she remains full-time employed during her studies or quits her job and focuses on her degree. If she continues to work full time and takes all her courses online, then ranking is the most important attribute, twice as important as price and three times as important as location. If she quits her job and attends school full time, then location becomes three times as important as ranking and twice as important as price. She is considering two universities, respectively, the MBA program at Arizona State University (ASU) and the MBA program at University of Phoenix (UOP), both of which are priced at approximately $25,000. She has rated each attribute on a scale of 1 to 100 for each of the two schools. a. Which of the two options should Roshima pursue of she wants to keep her full-time job? (Calculate the total expected utility from each school option and compare. Graph is not required) b. Which of the two options should she pick if she plans to quit her job and dedicate to her studies? c. Which option should she pursue if the probability of being laid off and unable to find a new job is estimated as  0.6? Show your calculations and explain your reasoning. 2. The demand function for Einstein Bagels has been estimated as follows: – 40.73Px + 84.17Py + 0.55Ax  where Qx represents thousands of bagels; Px is the price per bagel; Py is the average price per bagel of other brands of bagels; and Ax represents thousands of dollars spent advertising Einstein Bagels. The current values of the independent variables are , , and a. Calculate the price elasticity of demand for Einstein’s Bagels and explain what it means. b. Derive an expression for the (inverse) demand curve for Einsteins’s Bagels. c. If the cost of producing Einstein’s Bagels is constant at $0.10 per bagel, should they reduce price and thereafter, sell more bagels (assume profit maximization is the company’s goal)? d. Should Einstein Bagels spend more on advertising? 3. The consulting firm that you work for has been hired by the US Government to provide an independent analysis of the demand-side effects of a contemplated increase in the tax on gasoline. They provide you with a data set relating to the period 1962-1987, which they say contains valuable historic lessons relating to the impact of volatile pump prices due to the supply restrictions imposed by the Organization of Petroleum Exporting Countries (OPEC), and the Corporate Average Fuel Economy (CAFE) regulations that required car manufacturers to increase the fuel efficiency of the cars they sold, while at the same time Real Disposable Income (RDI) per capita was rising, the number of passenger cars (NPC) almost doubled, and inflation was pushing up the Consumer Price Index (CPI). Week 3 Relevant Costs. Two partners own together a small landscaping business in North Carolina, called Summer Lawn Care. They have been specializing in summer grass seeding, installation, and maintenance. Recently, the partners acquired special technology and know-how for winter grass installations and maintenance. They also added a tree cutting service as recent storms in the  area had caused demand for this service to soar. One of the partners insists that the name of the business should change to Lawn and Tree Care, so that it better reflects the range of services and, thus, generates more customer interest, and thus contracts. The second partner wants to keep the old name and argues, â€Å"We have already paid for business cards, vehicle paint, signage, and ads in Yellow Pages†. Evaluate the arguments of the two partners. Explain and illustrate their points by identifying the relevant and irrelevant costs for this decision. Contribution Analysis. Explain what is meant by â€Å"contribution analysis†.

Jennifer Trucking Company operates a large rig transportation business in Texas that transports locally grown vegetables to San Diego, California. The company owns 5 large rigs and hires local drivers paid fixed salaries monthly, regardless of the number of trips or tons of cargo that each driver transports each month. 2. The Palms Dry Cleaning Shop in Fort Lauderdale, Florida, faces a highly seasonal demand for its services, as the snow-birds retirees flock to Florida in mid-fall to enjoy the mild winter weather and then return to their main homes in mid-spring. Given this seasonality, Palms tries to keep the overhead costs as low as possible and therefore, often uses seasonal contracted labor to man its operations. The following table shows the labor costs in each month of operation over the past 12 months as well as the total number of garments that were dry-cleaned in each month. Palms pays fixed wages per hour to each employee, and we can assume that the costs of other variable inputs (such as chemicals, electricity, etc) have remained constant. 3. Over the past 12 months the Four Winds Novelty Company firm has recorded its internet sales (equals monthly output levels) and its monthly total variable costs (TVC) for a particular novelty item as shown in the following table. Sales have grown over this period with  relatively few shocks due to uncontrollable weather, political and sporting events. This online retailer carries no inventories; when it receives a pre-paid on-line order from a customer, it simply buys the product from a supplier and ships it out to the customer. Week 4 Strategic Behavior Oligopolies. An interesting example of strategic behavior comes from a 1997 article about Microsoft’s investment in Apple (New Straits Times, 1997). The article is included in the Required Readings list. Facing tough anti-trust scrutiny from government agencies, Microsoft provided financial support to Apple in order to ensure Apple’s survival and, therefore, to ensure that competitiveness in the industry remains. Moreover, the partnership with Apple provided an additional market for Microsoft’s products – the MS Office and the IE products were to be bundled with the MAC OS as one of the conditions for this financing. Discuss this case in the context of market structure and strategic behavior. What market structure do these firms operate in? Why did Microsoft need to preserve competitiveness in the industry? What was Microsoft afraid of in the event that Apple did not survive? Local Market Power. Bulls Eye department store specializes in the sales of discounted clothing, shoes, household items, etc. similar to the offerings at a regular Walmart or Target. Bulls Eye is the only department store in Show Low and the nearest other discount retailer is Target, located 49 miles away in Eagar. Bulls Eye, therefore, has some market power in its local area. Despite having some market power, Bulls Eye is currently suffering losses. An analyst at Bulls Eye is recommending to the manager to raise prices, so that profitability can be improved. The manager is unsure of this strategy as recent data points to increasing numbers of individuals shopping more and more. What are the pros and cons of raising the prices at Bulls Eye and would that strategy be profitable? Market Structures and Pricing Decisions Applied Problems. A small business which produces plastic vacuum-suction covers for round household dishes has  a monopoly that is protected by a utility patent. The market demand curve for this product is estimated to be: – 25P where Q is the number of plate covers per year and P is in dollars. Cost estimation processes have determined that the firm’s cost function is represented by + 2500Q -0.25*Q2. 2. Greener Grass Company (GGC) competes with its main rival, Better Lawns and Gardens (BLG), in the supply and installation of in-ground lawn watering systems in the wealthy western suburbs of a major east-coast city.Last year, GGC’s price for the typical lawn system was $1,995 compared with BLG’s price of $2,100. GGC installed 9,130 systems, or about 55% of total sales and BLG installed the rest. (No doubt many additional systems were installed by do-it-yourself homeowners since the parts are readily available at har dware stores.) Week 5 Good Will in Price Bidding. Sometimes, a bidder on a work contract may bid lower than what would maximize his/her profit from the contract and the reason for that is to create goodwill (to increase expected future business from the buyer). How would you value the goodwill that is obtained in this way? New Product Introduction. Bayer Schering Pharma AG, Germany owns the Alka-Seltzer, which was launched in 1931 and was meant for relief of minor aches, pains, inflammation, fever, headache, heartburn, sour stomach, indigestion, and hangovers. The Alka-Seltzer Plus was a spin-off of the original medicine, meant to relieve colds and flu. The company has recently introduced a new and improved Alka-Seltzer Plus, as described in the TV ad: â€Å"The Cold Truth†, (please, watch the ad listed in the Required Readings) Price Quotes and Pricing Decisions Applied Problems.

Coordination Chemistry of Bidentate Ligands Research

Coordination Chemistry of Bidentate Ligands Research Elham Torabi Farkhani Mehrdad Pourayoubi Pavel V. Avdreev Katarina Introduction The coordination chemistry of bidentate ligands has been studied for over thirty years [reference]. The bidentate ligands with phosphoryl and thiophosphoryl groups have been used as effective coordinating agents in the different metal chemistry, in most cases the reports were attributed to bonding between the metal cation and specific Lewis sites on the ligand, itself has number sites with potential to bind metal ions, such as nitrogen, sulfur and oxygen. In order to recent report Hg metal ion is known to have strong affinity for nitrogen and sulfur Lewis sites [reference] which our work here is done bonding between Hg metal atom and sulfur in ligands. A search of the Cambridge Structural Database (CSD) [reference] yielded a data set of 76 purely molecular structures to be used for study of coordination of metal atom with a P(S)[N][O]2 skeleton of ligand. Thus there are a number of reports on molecular structure contain M-S=P fragments with different metal atoms [reference]. An inves tigation of the reports reveals that there isn’t any publication with Hg metal, also we haven’t found any precise study on the effect of all interactions, including coordinating linkages and intermolecular interactions on the structure of Hg(II) complexes with bisthiophosphoryl ligands. Accordingly we have carried out a study on mercury (II) chloride with two different bidentate ligand with general formula (OEt)2P(S)-X-P(S)(OEt)2 where X=1,4-NH-C6H5-NH and piperazine (scheme ). Reaction of two ligand with HgCl2 generated binuclear complex C1 and C2. All compounds were charactrized by IR and NMR (1H, 13C and 31P NMR) spectroscopy and mass analysis. The structure of ligand 1 and two complexes C1 and C2 were determined by X-ray crystallography. Experimental Materials and methods Mercuric chloride (99.5%), O,O†²-diethyl chlorothiophosphate (OCH2CH3)2P(S)Cl (97%), diethylenediamine (97%), 1,4-phenylenediamine (99%) (Aldrich), acetonitrile (99%) and methanol (99%) (Merck) were used as supplied. Acetonitrile was dried with P2O5 and distilled prior to use. The 1H, 13C and 31P NMR spectra were recorded on a Bruker Advance 400 spectrometer at 400, 101 and 162 MHz, respectively. 1H chemical shifts were determined relative to Si (CH3)4. 31P chemical shift was measured relative to 85% H3PO4 as external standard. Mass spectra were performed using a Varian Star 3400 CX mass spectrometer. Infrared (IR) spectra were recorded on KBr disk using a Buck 500 scientific spectrometer. Elemental analysis was performed using a Thermo Finnigan Flash EA 1112 apparatus. X-ray data collection was performed with a Xcalibur, Sapphire3, Gemini diffractometer with graphite monochromator. Synthesis General procedure for the preparation of ligands The ligands were synthesized from the reaction of 2 mmol (OCH2CH3)2P(S)Cl with 1 mmol of the corresponding diamine (diethylenediamine and 1,4-phenylenediamine) in presence of Et3N as HCl scavenger in CH3CN at 0ËÅ ¡ C. After stirring for 24 h, the solvent was evaporated and the residue was washed with distilled water and dried. Chemical structures are shown in scheme 1.

Result and discussion IR and NMR spectroscopy Mass spectroscopy The nature of the fragments observed in the mass spectrum often provides as clue to the molecular structure. The fragmentation pathways of ligands 1 and 2 were studied by electron ionization at 70 eV experiment and revealed a molecular ion peak [M]+ at m/z (%) of 390 (28) and 412 (94) for 1 and 2, respectively. The formation of the [M-1] specie from the parent ion of compound 2 was shown to exclusively involve an aromatic hydrogen atom; our results were in good agreement with previously published results. [reference]. The previous paper has been shown that dialkyl alkanephosphonates ROCH2CH2P(O)(OR)2 undergo a McLafferty rearrangement in which a ÃŽ ³ hydrogen from the alkylphosphorous moiety migrates to the phosphoryl group and a molecule of olefin is eliminated from the molecular ion [reference]. The mass spectra of compound 1 and 2 with the same structure have confirmed previously reported mechanism. The peak related to the C2H4 radical-cation with m/z = 28 are shown for two struct ures. Relative peak height = relative abundance as measured from this ion in the compound 1 and 2 are 66 and 88. For the compound 1, the base peak is appeared at m/z = 153 (P(S)(OEt)2) and in the compound 2, the base peak is appeared at m/z = 411 (M-1) fragment. For 1, the main fragmentation is based cleavage of N-P bond then produced A ion and P(S)(OEt)2 with m/z 153. The ion of A following three pathways: (1): A ion can produce a stabilized ion by loss of ethylene via the McLafferty rearrangement which generate the odd mass ion m/z 181 that it operates for ion m/z 181 capable of electronic shift involving a six-membered cyclic transition state in the molecule skeleton given in scheme 1. This will then stabilize to an even mass ion m/z 180 by elimination of an H radical. (2): in this pathway produce the ion at m/z 147 that formed through a three- membered ring as transition state by loss of two molecule of ethanol. The ion of m/z 147 indicating the relatively low stability of the P-O bond to the molecule of A in comparison with that of the P-N bond. (3). The ion at m/z 84 is formed through two step, the first is cleavage of P-N bond then in second step is formed via a 1,2 hydride shift by loss of a molecule of P(S)(OEt)2 [reference]. The same kind of rearrangement is observed for 2 and the main fragmentation is based cleavage of N-P bond then produced molecule ion with m/z 107. Scheme 1. Fragmentation pathway of compound 1 X ray crystallography Complexes of 1 and 2 were crystallized in the orthorhombic space group Pbca Triclinic with space group P, respectively. Crystal data, data collection and structure refinement details are summarized in Table 1 and selected bond lengths and angles are given in Tables 2 and 3. The asymmetric unit of complexes of 1 and 2 consist of one Hg2+ ion, two Cl and one half crystallographically independent ligand (Fig 1). There are two different types of Hg-Cl bonds that included bridge Hg1-Cl2 bond (2.5904(17) Ã… in 1 and 2.4852 (7) Ã… in 2) connect the molecule into one dimensional chain extended along the c axis and terminal Hg1-Cl1 bond (2.369(2) Ã… in 1 and 2.4295 (9) Ã… in 2) linked to adjacent ones by intermolecular interaction into a chain parallel to b axis in 1 and a axis in 2. (Fig 2). So, the Hg atom adopts an Hg[Cl]3[S] coordination environment in this compound with the highly distorted tetrahedral geometry of the Hg(II) center that can be better described as a seesaw structure which two chloride atoms and Hg atom [ Hg1, Hg1, Cl2] is planar, one chloride and sulfur atoms in the pivot position. The different bond distance from the  µ-chloride atoms performed and refer to asymmetry of the halogen bonds (2.5904 (17), 2.6820 (17) Ã… in 1 an d 2.4852 (7), 2.8273 (8) Ã… in 2) and they are compared to the terminal bond of Hg-Cl slightly extended. Some selected bond angles specify the distorted tetrahedral geometry at the Hg(II) center in complex 1 are as follows: Cl1—Hg1—S1 130.91 (7) °, Cl1—Hg1—Cl2 110.98 (7) °, S1—Hg1—Cl2 104.59 (6) °, Cl1—Hg1—Cl2i 108.29 (8) °, S1—Hg1—Cl2i 105.96 (6) ° , Cl2—Hg1—Cl2i 87.47 (5) °, Hg1—Cl2—Hg1i 92.54 (5) ° and P1—S1—Hg1 98.40 (8) °. In ligand L1, the phosphorus atom has a distorted tetrahedral [N]P(S)[O]2 configuration with the bond angles in the range of 101.77 (18) ° [O2—P1—S1] to 115.80 (19) ° [O1—P1—S1]. The P=S bonds of ligand are in a trans orientation is showing respect to each other and that the sulfur atom is coordinated to the mercury center. As a result of coordination to the mercury center, as expected, the P=S bond length (P (1)–S (1) 1.97 (9) Ã…) is slightly longer than that of the free ligand The crystal structure of the complex 1 generated by the O1†¦S=P interaction along c-axis. As a result of these interactions, One-dimensional chain structure is produced. The presence of Hg-Cl and Hg-S moieties in the complex lead to the formation weaker intermolecular C-H†¦Cl-Hg , C-H†¦S-Hg interactions between the neighboring 1D chain along b-axis that create a two-dimensional array in the crystal lattice.
