A new bridging geometry for sulphur dioxide in [Mo(CO)2(PPh3)-(pyridine)(µ-SO2)]2·2CH2Cl2; X-ray crystal structure
Abstract
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.
