The ability of Fe4S4(SC6H5)4 2-/3- to cotransport electrons and hydrogen ions in a directional electron-transport system has been examined. A sequential electron-transport system was used, where aqueous CrIIdta was the electron donor, and (CH3N((C-H2)7CH3)3) 2Fe4S4(SC6H5)4 in toluene solution mediated the terminal reduction of methylviologen in aqueous solution. That Fe4S4(SC6H5)4 2-/3- mediated the electron transfer was demonstrated by using optical and EPR spectroscopies. The average molar ratio of electrons/hydrogen ions transported for 11 trials was found to be 1.18 ± 0.24. Valinomycin, a potassium ionophore, did not diminish the cotransport of hydrogen ions.
