Bis(tetra-n-butylammonium) Bis[(4-cyanophenyl)dithiocarbimato(2–)-S,S']nickel(II)

The title compound, [N(C4H9)4+]2.[Ni(C8H4N2S2)2]2−, crystallizes with the Ni atom on a crystallographic inversion center. The phenyl rings of the ligands make an angle of 50.50 (5)° with the plane spanned by the central nickel-sulfur fragment. The bond lengths do not indicate that the formal negative charge on the dithiocarbimato moiety is delocalized into the phenyl ring.
