(Chemical Equation Presented) Chemists are closing in on functional and structural models for the [FeFe] hydrogenases. Oxidation of [Fe 2(S2C2H4) (CO)3-(PMe 3)(dppv)] (dppv = cis-1,2-C2H2-(PPh 2)2) by one electron affords a mixed-valence model for the Hox state of the active site of the [FeFe] hydrogenases. Like the enzyme, this model exhibits the "rotated structure" and binds CO (see scheme). The radical character of the model is confirmed by its ready binding of NO.
