摘要：

Better than nature! A nickel(II) dithiolene complex [NiII(L 2-)(L-.)][PPh4] (1; see figure; L=1,2-dicarbomethoxyethylene dithiolate) electrocatalyzes hydrogen evolution at the lowest achievable reduction potential (Ered p, -0.69 V) in CH3CN and also in aqueous medium (E p, -0.71 V) to date. Compound 1 shows strikingly similar EPR and reduction potential values to those observed with native Ni-containing hydrogenases. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
