Paramagnetic [Ni('NMeS4')]2 1 ('NMeS4'2- = 2.2'-Bis(2-mercaptophenylthio)diethylmethylamine(2-)) was synthesized from Ni(ac)2 and Na2-'N MeS4' and characterized by X-ray structure analysis. In solid state, 1 contains two pseudo-octahedral [Ni('NMeS4')] fragments bridged via thiolate donors. In contrast to the parent complex [Ni('NHS4')]2, the thiolate and thioether donors coordinate cis to the Ni center forming meso [Ni('N MeS4')] fragments of CS symmetry. 1 readily dissociates in solution to
