The electrochemistry and spectroelectrochemistry of ((P)Nb)/sub 2/O/sub 3/, where P is the dianion of either octaethylporphyrin (OEP) or tetra-p-tolylporphyrin (TpTP), is reported in five different nonaqueous solvents. These NB(V) dimers may undergo up to three reductions and three oxidations depending upon the solvent/supporting electrolyte system and temperature. ESR measurements on the bulk-electrolyzed solutions are combined with electrochemical and spectroelectrochemical data to present an overall electrooxidation/reduction mechanism for the two dimeric complexes.
