Abstract

Abstract Reduction of a series of complexes derived from Co(CO) 3NO in which one or two carbonyl groups were substituted by other ligands was studied polarographically. It was found that in all cases the complexes are reduced reversibly to the radical anion which is irreversibly inactivated. The rate of the inactivation is comparable within the series studied so that the measured changes of half-wave potentials correspond to changes of standard redox potentials. A correlation of these quantitites with the NO stretching frequencies indicates a considerable degree of delocalization of the redox orbital.
