1-(4-Iodo-benz-yl)-3-methyl-pyridinium bis-(benzene-1,2-dithiol-ato)nickelate(III).

The asymmetric unit of the title compound, (C(13)H(13)IN)[Ni(C(6)H(4)S(2))(2)], contains half each of two centrosymmetric anions and a single cation in a general position. In the anions, the Ni(III) ions are surrounded by four S atoms in a distorted square-planar geometry. In the crystal, the anions exhibit two different packing modes by stacking along the a axis in face-to-face and side-by-side fashions. Inter-ionic C-H⋯S hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.6947†(5)†à ] are observed.
