ELECTROCHEMISTRY OF OXYGENATION CATALYSTS .2. IMPROVED SYNTHESIS, CRYSTAL-STRUCTURE, AND ELECTROCHEMICAL PROPERTIES OF N,N'-BIS(SALICYLIDENE)ETHYLENEDIAMINATOCOBALT(III) CHLORIDE

N,N'-Bis(salicylidene)ethylenediaminatocobalt(III) hydroxide is treate d with chloroform in methanol to yield the corresponding chloride in p ure, crystalline form. Results of the crystal structure determination compare well with those in earlier reports of dimeric [Co(salen)Cl]2 u nits and incorporated CHCl3 molecules. Electrochemical experiments in DMF and pyridine show that the chloride fully dissociates in these don or solvents. Thus, the quasireversible one-electron reduction to Co(sa len) is observed in cyclic voltammograms.
