E. Eichhorn et B. Speiser, ELECTROCHEMISTRY OF OXYGENATION CATALYSTS .4. SOLVENT-COMPOSITION-DEPENDENT ISOPOTENTIAL POINTS IN CYCLIC VOLTAMMOGRAMS OF CO(SALEN)+, Journal of electroanalytical chemistry [1992], 365(1-2), 1994, pp. 207-212
Isopotential points are described in multicycle voltammograms of icyli
dene)ethylenediaminato-cobalt(III)perchlorate in mixtures of dimethyl
formamide and pyridine. The potentials where these points occur vary w
ith the solvent composition. The results are discussed in terms of the
three-rung ladder scheme describing the electrode reaction with elect
ron exchanges (Co(II) half arrow right over half arrow left Co(III)) a
t the electrode surface and the successive exchange of two solvent mol
ecules per complex.
