Reactions of the bis(silyl)platinum(II) complexes [Pt(SiHPh2)2L2] (L = PMe3, PMe2Ph, PEt3; L-L = dppp (1,3-bis(diphenylphosphino)propane)) with organic isothiocyanates (RNCS) produced the dithiocarbonimidato complexes [Pt(S2CNR)L2] (R = Ph, p-tolyl, 2,6-Me2C6H3, i-Pr) or the diphenylsilanedithiolato complexes [Pt(S2SiPh2)L2], depending on the reaction temperature, the stoichiometry, and the nature of the phosphine ligand.
