The precious metal platinum was first used by indigenous peoples of South America, who found impure, native samples of it in the Au mines of what is now Ecuador and used the samples to make small items of jewelry. Platinum’s high melting point (1772oC) makes it harder to work than Au (1064oC) and Ag (962oC), but this same property and a high resistance to chemical attack make Pt suitable as a material for high-temperature crucibles. Although Pt is a noble metal, in the +4 and +2 states it forms a variety of compounds, many of which are coordination complexes. Its coordinating abilities make it an important catalyst for organic and inorganic reactions. The anticancer cisplatin (mentioned during lectures) can be prepared from K2PtCl6 via reduction with hydrazine (N2H4), giving K2PtCl4, followed by replacement of the 2 Cl ion ligands with NH3. Give the names to the three platinum compounds referred to. Draw coordination complex trans-Platinum diammine dichloride and label the Pt with its oxidation number. For Pt4+, draw energy level diagrams of the d-AOs and show orbital occupancy in both weak and strong octahedral fields. Calculate the total spin for each case. Calculate the CFSE (crystal field stabilization energy) in terms of Δ0 for each cas

The precious metal platinum was first used by indigenous peoples of South America, who found impure, native samples of it in the Au mines of what is now Ecuador and used the samples to make small items of jewelry. Platinum’s high melting point (1772oC) makes it harder to work than Au (1064oC) and Ag (962oC), but this same property and a high resistance to chemical attack make Pt suitable as a material for high-temperature crucibles. Although Pt is a noble metal, in the +4 and +2 states it forms a variety of compounds, many of which are coordination complexes. Its coordinating abilities make it an important catalyst for organic and inorganic reactions.
