Abstract
Voltammetry at a stationary platinum electrode and polarography were carried out in dichloromethane (0.1 mol dm-3 tetrabutylammonium perchlorate as supporting electrolyte) for complexes of the type [FeX(CNR)2L3][ClO4] [X = Cl, Br or I; L = PPh(OEt)2; R = phenyl, 4-methylphenyl, 4-methoxyphenyl, 2-methylphenyl or 2,6-dimethylphenyl] and for [Fe(CNR)3L3][ClO4]2 [L = PPh(OEt)2; R = cyclohexyl]. A mechanism of the redox process for both oxidation and reduction is postulated. A simple redox change without any complication from chemical reaction occurs in the case of oxidation at a platinum electrode, whereas the reduction is complicated by a subsequent chemical reaction. © 1982.
