摘要：

A solution of NiCl2 . 6 H2O in EtOH/H2O reacts with nBu3N and o-mercaptophenol to form [nBu3NH]2[Ni(SCrH4O)2] . EtOH (2) containing the nickel(II) complex [Ni(SC6H4O)2]2- (1). The molecular structures of 1 and its oxidation product, [Ni(SC6H4O)2]- (3), have been determined by X-ray diffraction. With respect to the chemical as well as electrochemical properties of the nickel sites of various hydrogenases, 3 is the first relevant model complex of coordination number four whose structural properties have been determined in different oxidation states.
