Bis[bis(diphenylphosphino)methane]platinum(II) salts: evidence for the formation of a five-co-ordinate bis[bis(diphenylphosphino)methane]-halogenoplatinum(II) cation
Abstract
The salts [Pt(dppm)2]X2(X = Cl, Br, I, PF6 or BPh4; dppm = Ph2PCH2PPh2) have been studied in solution by 1H, 31P, and 195Pt n.m.r. spectroscopy and by conductivity measurements. The halide salts are believed to form the five-co-ordinate cation [Pt(dppm)2X]+ in solution.
