Abstract

(Trichlorostannato)diphosphineplatinum(II) complexes of catalytic importance were investigated in the [BMIM][PF6] (BMIM = N-butyl-N′-methylimidazolium ion) ionic liquid by NMR. Formation of mononuclear [PtCl(diphosphine-I)(η1-diphosphine-II)]+ species involving monodentate coordination of one of the two diphosphines as well as dinuclear complexes [Pt2Cl2(diphosphine-I) 21-diphosphine-II)]2+ with a bridging bidentate phosphine was observed. Assignment of the structures is based on diagnostic 2J(P, P) and 1J(Pt, P) coupling constants obtained from typical second-order AMX 31P NMR spectra.
