Platinum is a chemical element; it has symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name originates from Spanish platina, a diminutive of plata "silver". [7] [8] Platinum is a member of the platinum group of elements and group 10 of the periodic table of ...
[9] [10] As well as with Karstedt's catalyst, Speier's catalyst enjoys widespread use for hydrosilylation, the main drawback is the deliquescent properties of the catalyst. [11] It is generally agreed that chloroplatinic acid is a precursor to the actual catalyst. A possible role for colloidal platinum or zero-valent complexes has also been ...
Cisplatin, PtCl 2 (NH 3) 2, is a coordination complex of platinum(II) with two chloride and two ammonia ligands.It is one of the most successful anticancer drugs. A coordination complex is a chemical compound consisting of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands ...
Chloropentammineplatinum chloride is an inorganic compound with the formula [PtCl(NH 3) 5]Cl 3. It is a chloride salt of the coordination complex [PtCl(NH 3) 5] +. It is a white, water soluble solid. The compound is prepared by treating potassium hexachloroplatinate with aqueous ammonia: [1] K 2 PtCl 6 + 5 NH 3 → [PtCl(NH 3) 5]Cl 3 + 2 KCl
Sodium hexachloroplatinate is obtained as an intermediate in the preparation of Pt complexes, often starting with the dissolution of platinum in aqua regia, giving hexachloroplatinic acid, which is then reacted with sodium chloride and evaporated, leaving the salt behind. [3] Pt + 4 HNO 3 + 6 HCl → H 2 [PtCl 6] + 4 NO 2 + 4 H 2 O
