Abstract
- The reaction of 1-[(2-carboxyethyl)benzene]-3-[benzothiazole]triazene (HL) and CuCl gives a trinuclear copper(I) complex, [Cu I 3 (L)(L′) 2 ]·THF ( 1 ·THF) (L′ = the 1-[(2-carboxymethyl)benzene]-3-[benzothiazole]triazene ion), which has been structurally characterized by X-ray crystallography. Electrochemical studies indicate that this complex can catalyze hydrogen evolution from a neutral buffer with a turnover frequency of 355 (pH 7.0) moles of hydrogen per mole of catalyst per hour at an overpotential of 789 mV vs SHE. Sustained proton reduction catalysis occurs at a glassy carbon (GC) electrode to give H 2 over a 72 h electrolysis period with 94.4% Faradaic yield and no observable decomposition of the catalyst.
