Thiolate complexes of osmium(III) and osmium(IV). Crystal structures of [Os(SC6F5)2(O2CPh)(PMe2Ph)2] and [OsCl-(SC6F5)3(PMe2Ph)]

Abstract

Treatment of [Os(SR)3(PMe2Ph)2](R = C6F5 or C6HF4) with PhCO2H or with HCl in acetone gives, respectively, the red paramagnetic osmium(III) derivatives [Os(SR)2(O2CPh)(PMe2Ph)2]1 and the green, five-co-ordinate, diamagnetic osmium(IV) complexes [OsCl(SR)3(PMe2Ph)]2. X-Ray crystallography has shown that 1(R = C6F5) has an octahedral structure with trans-thiolates, cis-phosphines and a chelating benzoate ligand and that 2(R = C6F5) has a trigonal-bipyramidal structure with thiolates in the equatorial plane.
