Novel co-ordination of sulphur dioxide. The crystal and molecular structure of nitrosyl(sulphur dioxide)bis(triphenylphosphine)rhodium
Abstract
Crystals of [Rh(NO)(SO2)(PPh3)2] have been obtained from SO2-saturated solutions of Rh(NO)(PPh3)3 in benzene–heptane mixtures; the X-ray crystal structure shows the SO2 ligand co-ordinated to the rhodium through the sulphur atom and through one of the oxygen atoms, while the RhNO angle is 140°.
