The dithiocarbamate anions in the title compound, [Ni(C 7 H 14 NS 2 ) 2 ], chelate to the Ni II atom, which is four- coordinate in a square-planar geometry. The Ni II atom lies on a center of inversion. Related literature For nickel bis(diethyldithiocarbamate) and nickel bis(di- butyldithiocarbamate), see: Bonamico et al. (1965); Khan et al.
