dc.description.abstractA tris(N-pyrrolidinyl)phosphine (P(NC4H8)(3)) monosubstituted complex, [(mu-pdt)Fe-2(CO)(5)P(NC4H8)(3)] (2) was synthesized as a functional model of the hydrogen-producing capability of the iron hydrogenase active site. The structure was fully characterized by X-ray crystallography. IR and electrochemical studies have indicated that the P(NC4H8)(3) ligand has better electron-donating ability than that of those phosphine ligands, such as PMe3, PTA (1,3,5-triaza-7-phosphaadamantane), PMe2Ph PPh3, and P(OEt)(3). The electrocatalytic activity of 2 was recorded in CH3CN in the absence and presence of weak acid, HOAc. The cathodic shift of potential at -1.98 V and the dependence of current on acid concentration have indicated that complex 2 can catalyze the reduction of protons to hydrogen at its (FeFe1)-Fe-0 level in the presence of HOAc. IR spectroelectrochemical experiments are conducted during the reduction of 2 under nitrogen and carbon monoxide, respectively. The formation of a bridging CO group during the reduction of 2 at -1.98 V has been identified using IR spectroelectrochemical techniques, and an electrocatalytic mechanism of 2 consistent with the spectroscopic and electrochemical results is proposed.
