Spectroscopic data of 1 suggests a 2+ oxidation state for the Fe ion in the [Fe]-hydrogenase. Complex 1 serves as a precursor to other hydrogenase models.Cluster-Free HydrogenaseCrystal-StructureOnly HydrogenaseSulfur ProteinsModelCoordinationSpectroscopy2-PyridoneChemistryEvolutionAn Iron Carbonyl Pyridonate Complex Related to the Active Site of the [Fe]-Hydrogenase (Hmd)text::journal::journal article::research article
