Abstract

Oxidation of the nominally all-ferrous hexanuclear cluster ( ^HL)₂Fe₆ 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 ( ^HL)₂Fe₆Br₆. 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 Fe₆ core electronic structure.
