Abstract : Dissymetrically disubstituted di-iron azadithiolate complexes [Fe2(CO)4(κ2-LL){μ-SCH2N(iPr)CH2S}] (LL = dppe, phen) protonate exclusively at the N atom of the bridge, like the hexacarbonyl precursor but in contrast to symmetrically disubstituted analogues; substitution of dppe for two CO groups noticeably increases the kinetics of the electrocatalytic proton reduction process.
