Redox behaviors of [Fe4S4(SR)4]2- and [Mo2Fe6S8X3(SR)6] 3- (R = C6H4-p-n-C8H17; X = SEt, OMe) in aqueous micellar solutions

Iron-sulfur and molybdenum-iron-sulfur clusters with p-n-octylbenzenethiolate as a ligand, [Fe4S4(SR)4]2- (1) and [Mo2Fe6S8X3(SR)6] 3- (R = C6H4-p-n-C8H17; X = SEt (2), OMe (3)) have been prepared. The redox potentials of 1-3 in nonionic, cationic, and anionic micellar solutions at pH 7.0 fall in the range -0.58 to -0.63 V (vs. SCE), which are very close to those of 4-Fe and 8-Fe ferredoxins in H2O. Proton concentrations markedly influence the redox potentials of those clusters in the range of pH 4-9, -60 and -30 mV/pH unit for the iron-sulfur and molybdenum-iron-sulfur clusters, respectively, whereas above pH 10 the redox potentials are essentially constant, suggesting the existence of an equilibrium between the protonated and deprotonated clusters in aqueous micellar solutions below pH 10.
