described briefly. The metal oxidation as well as ligand reductions for the complexes have been studied electrochemically in acetonitrile using different working electrodes. It has been shown, for the mixed L–bipy complexes, that the reductions of co-ordinated L occur at comparatively lower negative potentials. The correlation between the electrochemical properties and vc.t.(absorption) is discussed.
