Abstract
One-electron reduction of the synthetic tetramers [Fe4S4(SR)4]2- (R = CH2Ph, Ph), by chemical and electrochemical methods affords the corresponding trianions. The collective results from optical, electron paramagnetic resonance, and Mössbauer spectroscopy, when compared to available data for reduced 4-Fe and 8-Fe ferredoxin proteins and super-reduced Chromatium high-potential protein, reveal that [Fe4S4(SR)4]3- are electronic analogs of the [Fe4S4(S-Cys)4] active sites of these proteins.
