• Reaction of ligand, H2L and MoCl5 gives a Mo(VI) complex [MoL(O)2] 1.
• Structure of 1 is determined by single crystal X-ray diffraction analysis.
• Complex 1 can catalyze hydrogen evolution from acetic acid and water.
• Sustained catalysis occurs over a 72 h period and no decomposition of 1.
Reaction of 2-pyridylamino-N,N-bis(2-methylene-4-methoxy-6-tert-butylphenol) (H2L) and MoCl5 gives a Mo(VI) complex [MoL(O)2] 1, which has been determined by X-ray crystallography. Electrochemical studies show that complex 1 can catalyze hydrogen evolution from acetic acid with a turnover frequency (TOF) of 39 (DMF) mol/h at an overpotential of 642 mV and from water with a TOF of 360 (pH 7.0) mol/h at an overpotential of 907 mV. Sustained proton reduction catalysis occurs at glassy carbon (GC) electrode from water to give H2 over a 72 h electrolysis period and no observable decomposition of the catalyst.
