In CH2Cl2 solution the complex cis, trans-Mo(CO)2(PPh3)2(pyridine)(η2-SO2)(1) reacts to give a dinuclear complex (2); an X-ray crystal structuree determination shows that the moly-bdenum atoms are bridged by two SO2 ligands that are co-ordinated to one metal through the sulphur atom and one oxygen atom and to the second metal via thee remaining oxygen atom.
