Abstract

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. H-1 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.
