A number of Cp*PtMe₂X and Cp*PtMe₂(L)⁺ (OTf)^- complexes have been prepared [Cp* = η⁵-C₅Me₅ ; OTf = OSO₂CF₃ ; X = OTf, I, N₃, S(p-tol) ; L = CO, C₂H₄, CH₂=CHMe, NH₃, NH₂Bu¹]. The complexes Cp*PtMe₂(CO)⁺ (OTf)^-, Cp*PtMe₂(C₂H₄)⁺ (OTf)^-, and Cp*PtMe₂(CH₂=CHMe)⁺(OTf)^- represent a rare type of compound in which a n acid ligand is coordinated to a high valent metal center predominantly through σ-donation and π-backbonding plays only a limited role in the metal-ligand interaction. The arylthiolate complex, Cp*PtMe₂[S(p-tol)], has been structurally characterized by X-ray diffraction.
