Hexacarbonyldiiron bridged by a 1,1'-dithiolatoferrocene, [Fe(C5H4S)(2){Fe(CO)(3)}(2)] (1), was synthesized, and the electrochemistry showed reversible oxidation at the Fe(C5H4S)(2) site and quasi-reversible reduction at the hexacarbonyldiiron site. Spectroelectro-chemical techniques showed reduction-induced ligand isomerization, where the thiolate ligand went from bridging to terminal and one carbon monoxide ligand moved to a quasi-bridging position. This mechanism was further supported by cyclic voltammetry simulation and density functional theory calculations. Complex 1 showed electrocatalytic activity toward hydrogen-evolving reaction.
