Abstract
The complexes M2(O2Cme)4x2(M = Os, X = Cl; M = Rh, Z = MeOH) react with triphenylphosphine in acetic acid leading to partial replacement of acetate groups by triphenylphosphine ligands in which ortho-metallation has occurred at one of the phenyl rings on each phosphine; the isolated products, M2(O2 CMe)2[Ph2P(C6 H4]2X2, M = Os, M = Cl; M = Rh, X = MeCO 2H) have been characterized by X-ray crystallography, showing that each complex has a central M2L8core consisting of the dimetal unit bridged, in a cisoid arrangement, by two acetate groups and two ortho-metallated triphenylphosphine legands.Keywords
