Diphenylphosphineacetic acid (HA) acts as a monodentate P-donor towards divalent platinum; the anion acts as a bidentate P,O-donor. Three types of complexes have been prepared, PtX2(HA)2, PtXA(HA) and PtA2 (X = Cl, Br, I, SCN), whose formation is determined primarily by the type of X, the acidity of the medium and the polarity of the solvent. It follows from electronic, infrared and 31P-NMR spectra that all the prepared complexes are cis-square planar in structure.
