Nucleophilic attack at the carbon atom of a dithiocarbene ligand by coordinated carbon disulphide: The molecular structure of [(dppe)IPt(μ-C(S)SC(SMe)2)Pt(dppe)]+I− (dppe=1,2-bis(diphenylphosphino)ethane)

Reaction of the complex [Pt(η2-CS2)(dppe)] [dppe=1,2-bis(diphenylphosphino)ethane] with excess methyl iodide results in the formation in high yield of the dimeric complex [(dppe)IPt(μ-C(S)SC(SMe)2)Pt(dppe)]+I−·C7H8·Et2O, the crystal structure of which has been determined. Crystals of the complex are monoclinic, space group P21/c, with Z=4, in a unit cell with lattice parameters a=21.082(4), b=17.304(3), c=21.423(3) Å, and β=116.62(1)°. The …
