The reaction of NiCl2·6H2O with sodium 2,2-dicyanoethene-1,1-dithiolate [Na2(i-mnt)] in dimethyl sulfoxide produces the title complex, [Ni(C2H6OS)6][Ni(C4N2S2)2]. There is half each of an [Ni(C2H6OS)6]2- complex anion and an [Ni{(CH3)2SO}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 molecules as ligands.
