Infrared and Raman studies of halogenotrimethylplatinum(IV) complexes and related compounds

Abstract

I.r. and Raman spectra of a series of platinum(IV) complexes of general type [R₂(R′)XPtL₂](R = Me or CD₃; R′= Me, CD₃, CF₃, MeCO, PhCH₂, or CH₂:CH·CH₂; X = Cl, Br, or I; L = phosphine or arsine) are reported, and bands due to ν(Pt–CH₃) and ν(Pt–X) have been unambiguously assigned. Group trends are correlated to changes in X and L, and the effect of progressive deuteriation has been observed. Scrambling of Me and CD₃ groups has been conveniently followed by identifying Pt–C stretching frequencies in the Raman spectra.
