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.
