[Ethylene-1,2-bis(diphenylphosphine)-P,P′]dinitratoplatinum(II) and cis-bis[(diphenylphosphinomethyl)-diphenylphosphine oxide-O,P]-platinum(II) dinitrate dihydrate

On [Pt(dppe)(NO3)2], where dppe is ethylene-1,2-bis(diphenyl-phosphine) (C26H24P2), the Pt atom is coordinated by the two P atoms and by two O atoms of the two nitrate ions. The molecule has a distorted square-planar geometry, with one of the nitrate groups directed on each side of the plane. The cation in cis-[Pt(dppmO-O,P)2](NO3)2· 2H2O, where dppmO is bis(diphenylphosphinomethyl)diphenylphosphine oxide (C25H22OP2), comprises two five-membered chelate rings, each dppmO ligand being coordinated to platinum through one P atom and the O atom. The larger P-Pt-P angle of 102.25 (4)° is due to steric interactions between the two phenyl groups on each P atom.

Studies on Pt-S bonds. Methylsulfanyl-acetato, -benzoato and -phenolato complexes of the Pt(II)(PPh3)2 and Pt(II)(dppe) moieties and the crystal structure of bis-triphenylphosphine(methylsulfanylacetato)platinum(II) nitrate

Bis-triphenylphosphine and bis(diphenylphosphine)ethane platinum(II) complexes with the chelating anionic ligands methylsulfanyl-acetato (sa), -benzoato (sb) and -phenolato (sph) have been synthesised and characterised. Infrared and multinuclear NMR spectra are in accordance with chelation of these ligands through the sulfur and the anionic oxygen atoms. The structure of [Pt(PPh3)2(sa)]NO3 has been determined through X-ray diffraction and confirms chelation of sa. 1H NMR spectra suggest that the chelate ring in this compound is rigid, with the same conformation found in the solid state, while in the analogous dppe complex both chelate rings undergo inversion of conformation at room temperature.
