Abstract

Abstract Oxidation of cis-[Mo(CO) 2(bipy) 2] (bipy = 2,2′-bipyridine) by silver(I) salts, AgX (X = NCS, NO 2, NO 3) in acetonitrile solution at room temperature has been found usually to result in the displacement of one bipy ligand by the nucleophile, X. The products have been characterised as cis-[Mo(NCS) 2(CO) 2(bipy)(NCMe)], [MO(η 2-NO 3)(CO) 2(bipy)][NO 3] and [Mo(NO 3)(CO) 2(bipy) 2][NO 3] by microanalysis, conductivity measurements and spectroscopy (IR, 1H NMR, electronic absorption). These results are compared with those for oxidation of cis-[Mo(CO) 2(dmpe) 2] (dmpe = ethanediylbis(dimethylphosphine)) and can be explained in terms of the basicity of X which increases in the order X = NO 3 − < NO 2 − < NCS −.
