Fragmentation of co-ordinated carbon disulphide and dithiocarbene ligands by nucleophilic attack at carbon: the crystal structure of [(Ph 3 P)IPt(µ-SMe)(µ-CSMe)PtI(PPh 3 )]·Me 2 CO

Nucleophilic attack at the carbon atom of carbon disulphide in the complex [Pt(η2-CS2)(dppe)][dppe = 1,2-bis(diphenylphosphino)ethane] by the zero-valent platinum complex [(Pt(η2-C2H4)(PPh3)2] results in the formation of the dinuclear platinum thiocarbonyl complex [(dppe) [graphic omitted]t(PPh3)(CS)](2). A similar attack at the carbon atom of the dithiocarbene ligand in either of the complexes [PtI(PPh3)2{C(SMe)2}]+I–(3) or …
