Abstract
The reaction between 2 mol equiv. of [Hg(SiMe3)2] and [PtCl2{(Ph2P)2CH2}] gives the complex [Pt(SiMe3)2{(Ph2P)2CH2}](I), whilst with a deficiency of [Hg(SiMe3)2] a bright red air-sensitive platinum(IV) complex can be isolated having the composition [Pt(HgSiMe3)2(SiMe3)2{(Ph2P)2CH2}](II); this slowly decomposes in solution to give (I), mercury, and Si2Me6. Under different experimental conditions the reaction produces a yellow air-stable platinum(I) complex, [Pt2Cl2{(Ph2P)2CH2}2](III). Diphenylmercury also combines with [PtCl2{(Ph2P)2CH2}] forming [Pt(HgPh)2Ph2{(Ph2P)2CH2}].Keywords
