Preparation, characterization and electrochemistry of an iron-only hydrogenase active site model covalently linked to a ruthenium tris(bipyridine) photosensitizer

• An NH2-functionlized [Fe2S2] model complex of the iron-only hydrogenase active site was covalently linked to the tris( bipyridine) ruthenium photosensitizer. The [RuFeFe] trinuclear complex 1 was characterized by MS, IR, UV-vis, H-1 & C-13 NMR spectra. A quasi-reversible reduction peak at - 1.41V versus Ag/Ag+ for the (FeFeI)-Fe-I/(FeFe0)-Fe-I process is observed in the cyclic voltammogram of 1.
