Abstract

Mössbauer spectroscopy of the synthetic tetramers [Fe4S4(SR)4]2- (R = alkyl, aryl) and the corresponding trianions obtained by one-electron reduction, when compared with available data for 4-Fe and 8-Fe iron-sulfur proteins, shows that these tetramers are electronic analogs of the active sites of the proteins.
