title: Electrocatalytic proton reduction catalyzed by a dimanganese disulfide carbonyl complex containing a redox-active internal disulfide bond.
abstract: A dimanganese hexacarbonyl complex [(Mn(CO)3)2(μ-SC6H4-o-S-S-C6H4-o-μ-S-)] containing an elongated disulfide bond electrocatalyses proton reduction at moderate overpotentials of 0.55 to 0.65 V. Cyclic voltammetric, infrared spectroscopy and computational studies suggest that the redox-active sulfur atoms of the disulfide bond serve as the initial reduction site.
