Abstract

The elect;rochemical reduction of Fe2(salen)2O at a platinum electrode in dimethylsulfoxide is investigated using the techniques of cyclic voltammetry, controlled potential coulometry and chronoamperometry. The effects of concentration and addition of a proton source on the reduction mechanisrn are investigated. The reduction proceeds by two related mechanisms. At short-times, Fe2(salen)2O is reduced by two sequential one-electron steps producing an Fe(III)Fe(II) dimer and an unstable Fe(II) dimer. At long-times the mixed-valence dimer reacts leading to transfer of 1.5 electrons per Fe2 unit. Mechanisms consistent with the experimental data are proposed involving the formation of a tetrameric structure.
