N2 - The complex [CoII(qpy)(OH2)2]2+ (qpy = 2,2′:6′,2′′:6′′, 2′′′-quaterpyridine) is an efficient visible light-driven catalyst for both water oxidation and reduction. It catalyses photochemical oxygen evolution from water at pH 8.0 with [RuII(bpy) 3]2+/S2O82- (λ = 457 nm, max TON = 335, bpy = 2,2′-bipyridine). It also catalyses photochemical hydrogen generation from [IrIII(dF(CF 3)ppy)2(dtbbpy)]+/TEOA (dF(CF3)ppy = anion of 2-(2,4-difluorophenyl)-5-trifluoromethylpyridine, dtbbpy = 4,4′-di-tert-butyl-2,2′-bipyridine, TEOA = triethanolamine) in aqueous acetonitrile (λ > 420 nm, max TON = 1730).
