Description
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.
