title: Hexa-kis-(dimethyl sulfoxide-κO)nickel(II) bis-(2,2-dicyano-ethene-1,1-dithiol-ato-κS,S')nickelate(II).
abstract: The reaction of NiCl(2)·6H(2)O with sodium 2,2-dicyano-ethene-1,1-dithiol-ate [Na(2)(i-mnt)] in dimethyl sulfoxide produces the title complex, [Ni(C(2)H(6)OS)(6)][Ni(C(4)N(2)S(2))(2)]. There is half each of an [Ni(C(2)H(6)OS)(6)](2-) complex anion and an [Ni{(CH(3))(2)SO}(6)](2+) complex cation in the asymmetric unit. The i-mnt ligand coordinates in a bidentate manner to the Ni atom in the anion through the two chelating S atoms in an approximate square-planar geometry. The Ni atom in the complex cation has an octahedral coordination environment with six dimethyl sulfoxide mol-ecules as ligands.
