Abstract:
Clusters of composition [Pt(PPh2)]n, n = 6−10, have been synthesized by reduction of a series of PtII complexes [(PPh3)Pt (OAc)G]m (G = (OAc)2 · PdC3H5, m = 1; G = Cl, OAc, (OAC)2Ag, m = 2) with H2, HCOOH and Na-amalgam. A hydridophosphide PdII complex [Pd2(PPh2)Hx]n was obtained in an analogous manner by reduction of [(PPh3)Pd(OAc)2] 2 with HCOOH. Additionally a complex with diphenylphosphonic acid as a ligand [Pd(μ-O2PPh2)(C6H5)(PPh3)]2 was obtained and characterized with X-ray data. The formation of O2PPh2 anion under strictly anaerobic reductive conditions implies the transfer of an O atom from the carboxylic ligand to the P atom of the phosphorus-containing ligand. Cleavage of the CPh bond seems to be a common process for the reductive reactions of both Pd and Pt phosphine complexes. Phosphide clusters of compositions [Pt(PPh2) n, and [Pd2(PPh2)Hx]n were characterized with IR, SAXS, EXAFS and NMR data and molecular mass measurements.
