spectroscopic characterization of the chiral phosphidophosphine, diphosphine dimeric complex [Pt2Cl3(R*)-μ-iPrPCH2PiPr2}(R*)-μ-HiPrPCH2PiPr2}] (3a) is reported. The further isolation of [PtCl2(HiPrPCH2PiPr2)] (1) and [Pt2Cl3(R*)-μ-iPrPCH2PiPr2}(R*)-HiPrPCH2PiPr2}] (2b) has led to a rationalization of the racemate's, 3a, predomination, over other potential isomers, e.g. [Pt2Cl3(R*)-μ-iPrPCH2Pi
