Abstract

Neutral Bi(III) complexes of a series of phosphinothiol ligands, 2-(Ph 2P)C 6H 4SH, 2-(Ph 2P)6-(Me 3Si)C 6H 3SH, PhP(C 6H 4SH-2) 2 and P(C 6H 4SH-2) 3 have been prepared by direct reaction of bismuth(III) chloride and the appropriate ligand in methanol in the presence of triethylamine. All compounds were characterized by microanalysis, FAB mass spectrometry, IR, 1H and 31P NMR spectroscopy. The crystal structure of the complex [Bi{2-(Ph 2P)C 6H 4S} 3] was determinated by X-ray diffraction. The bismuth ion is hexacoordinated by three anionic phosphinothiolate ligands, which act in a bidentated chelating (S,P) manner. The coordination geometry around the metal ion can be described as distorted octahedral.
