Iron complexes containing tetradentate monophenolate ligands have been found to be highly active for the electrocatalytic reduction of protons to hydrogen gas. Catalysis occurs at -1.17 V vs SCE in CH3CN with a turnover frequency of up to 1000 s-1 and a 660 mV overpotential. Interestingly, the catalyst activity is enhanced in the presence of water, achieving turnover frequencies of 3000 s-1 with an overpotential of 800 mV, making it one of the most active iron electrocatalysts currently reported. The catalyst is also capable of generating hydrogen from purely aqueous buffer solutions of pH 3-5 with Faradaic efficiencies of 98%.

Reaction of the tetradentate ligand N-(2-hydroxybenzyl)-N,N-bis(2- pyridylmethyl)amine (L-OH) with MoO2Cl2 in methanol in the presence of NaOMe and PF6- results in the formation of [MoO2(L-O)]PF6. Similarly, the reaction of N-(2-mercaptobenzyl)-N,N-bis(2-pyridylmethyl)amine (L-SH) with MoO 2(acac)2 leads to the formation of [MoO 2(L-S)]+. The dioxo-molybdenum complex [MoO 2(L-O)]+ reacts with phosphines in methanol to afford phosphine oxides and an air-sensitive molybdenum complex, tentatively identified as [Mo(IV)O(L-O)(OCH3)]. The latter complex is capable of reducing biological oxygen donors such as DMSO or nitrate, thereby mimicking the activity of DMSO reductase and nitrate reductase. Reaction of [MoO2(L-O)] PF6 with PPh3 in other solvents than methanol leads to the formation of the Mo(V) dimer [(L-O)OMo(μ-O)MoO(L-O)](PF6) 2. The crystal structures of [MoO2(L-O)]PF6 and the μ-oxo bridged dimer are presented. The Royal Society of Chemistry 2005.
