The reactions of SO2 with halocarbonyl anions of rhodium and iridium [M(CO)2X2](1-) (M = Rh, Ir; X = Cl, Br, I), were studied. Addition of neutral ligands, Ph3E (E = P, As, Sb) or pyridine, to the SO2 treated halocarbonyl solution resulted in the formation of various complexes according to the nature of the precursor complex and the ligand. The obtained complexes are formulated as Rh(CO)(SO2)(Ph3As)2Cl, [Rh(py)2(SO2)Cl].2H2O, Rh(CO)(SO2)(Ph3P)2Br, Rh2(CO)2(SO2)(Ph3Sb)2Br2, Rh(py)2(SO2)2I(C2H5OH), Rh(SO2)3I(C2H5OH) and Rh2(CO)2(SO2)3(Ph3Sb)2I2, Ir(SO2)2Br(H2O)2, [Ir(SO2)4(Ph3Sb)Br].6H2O, Ir(SO2)I(H2O)2 and [Ir(SO2)2(Ph3As)I3].4H2O. All complexes obtained have been characterized by physico-chemical methods.
