Abstract

We report a synthetic nickel complex containing proton relays, [Ni(P^Ph₂N^C₆H₄OH₂)₂](BF₄)₂ (P^Ph₂N^C₆H₄OH₂ = 1,5-bis(p-hydroxyphenyl)-3,7-diphenyl-1,5-diaza-3,7-diphosphacyclo-octane), that catalyzes the production of H₂ in aqueous acetonitrile with turnover frequencies of 750–170 000 s⁻¹ at experimentally determined overpotentials of 310–470 mV.
