In situ FTIR, UV-vis, and ESR spectroelectrochemistry were combined with microvoltammetry and classical electrochemical techniques in order to elucidate the prevailing electron-transfer mechanism for the oxidation and reduction of (TPP)Ru(CO) (where TPP is the dianion of tetraphenylporphyrin) in six different nonaqueous solvents. (TPP)Ru(CO) undergoes four reversible oxidation/reduction reactions at a 25-{mu}m microelectrode. All four electrode reactions were investigated with respect to the site of electron transfer, the stability of the electrooxidation/reduction product, the fate of the axially bound CO ligand, and the presence or absence of other axial ligands.
