✦ Synopsis
Mononuclear Nickel Thiolate Complexes Containing Nickel Sites in Different Oxidation States: Molecular Definition of [Ni(SC~6~H~4~O)~2~]^2−^ and [Ni(SC~6~H~4~O)~2~]Herrn Professor Dietrich Mootz zum 60. Geburtstag gewidmet.
A solution of NiCl~2~·6 H~2~O in EtOH/H~2~O reacts with __n__Bu~3~N and __o__1‐mercaptophenol to form [__n__Bu~3~NH]~2~[Ni(SC~6~H~4~O)~2~]·EtOH (2) containing the nickel(II) complex [Ni(SC~6~H~4~O)~2~]^2−^ (1). The molecular structures of 1 and its oxidation product, [Ni(SC~6~H~4~O)~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.
