Diironmodelcomplexes (μ-pdt)Fe2(CO)5L with L = pyridine ligands, e.g. py (A), etpy (B), btpy (C), were synthesized as active site analogues of [FeFe] hydrogenase, and characterized by X-ray crystallography and electrochemistry. Pyridine-N ligation was found to be able to tune the redox properties of the diiron centers of modelcomplexes.
