Dynamic ligation at the first amine-coordinated iron hydrogenase active site mimic.
The first model of the iron hydrogenase active site has been prepared in which an amine ligand is loosely coordinated to an Fe(i) centre, and can be replaced by a solvent molecule; irrespective of the ligand set, the one electron reduction of both complexes is chemically reversible and is shown to proceed through the same species which features a bridging CO ligand.
