The mono-substituted complex [Fe-2(CO)(5)(-naphthalene-2-thiolate)(2)(P(PhOMe-p)(3))] was prepared taking after the structural principles from both [NiFe] and [FeFe]-hydrogenase enzymes. Crystal structures are reported for this complex and the all carbonyl analogue. The bridging naphthalene thiolates resemble -bridging cysteine amino acids. One of the naphthyl moieties forms - stacking interactions with the terminal bulky phosphine ligand in the crystal structure and in calculations. This interaction stabilizes the reduced and protonated forms during electrocatalytic proton reduction in the presence of acetic acid and hinders the rotation of the phosphine ligand. The intramolecular - stabilization, the electrochemistry and the mechanism of the hydrogen evolution reaction were investigated using computational approaches.
