Ditertiary phosphines bearing a –N–C–C(O)–N(H)– linker and their corresponding dichloroplatinum(II) complexes

Abstract

The preparation of a small library of new –N–C–C(O)–N(H)– modified ditertiary phosphines is reported along with their square-planar dichloroplatinum(II) complexes. All compounds were characterized by 31P{1H} and 1H NMR spectroscopy, FT–IR spectroscopy and elemental analysis. The single crystal X-ray structures of four PtII complexes have been determined. Intra- (N–H···N) and intermolecular (N–H···N) hydrogen bonding is principally observed.
