Abstract

In the title salt, (C(13)H(10)N(3)O(2))[Ni(C(3)S(5))(2)], the Ni(III) cation is S,S'-chelated by two 2-thioxo-1,3-dithiole-4,5-dithiol-ate anions in a distorted square-planar geometry. The complex anion is approximately planar with a maximum deviation of 0.097 (1) Å. In the 1-(4-nitro-benz-yl)-4-cyano-pyridinium cation, the pyridine ring is twisted at a dihedral angle of 73.84 (16)° with respect to the benzene ring. π-π stacking is observed between nearly parallel [dihedral angle = 4.71 (7)°] dithiole and benzene rings, the centroid-centroid distance being 3.791 (2) Å.
