ABSTRACT

Oxidation of the nominally all-ferrous hexanuclear cluster ((H)L)(2)Fe(6) with six equivalents of ferrocenium in the presence of bromide ions results in a six-electron oxidation of the Fe(6) core to afford the nominally all-ferric cluster ((H)L)(2)Fe(6)Br(6). The hexabromide cluster is also structurally characterized in a 4+ core oxidation state. A structural comparison of these two clusters provides an insight into the Fe(6) core electronic structure.
