Different spin states characterize the two Fe atoms in the unique asymmetric dinuclear complex 1 , as confirmed by Mössbauer spectroscopy. The complex is a first generation structural model for [Fe]‐only hydrogenases; it incorporates both a sulfur‐rich environment and coordinated carbon monoxide ligands, as observed in [NiFe]‐hydrogenases. The IR vibrations of the carbonyl ligands in 1 compare well with those of the [Fe]‐only hydrogenases.
