1-(3,4-Dichloro-benz-yl)pyridinium bis-(2-sulfanyl-idene-1,3-dithiole-4,5-dithiol-ato-κS,S')nickelate(III).

The title compound, (C(12)H(10)Cl(2)N)[Ni(C(3)S(5))(2)], is an ion-pair complex consisting of 1-(3,4-dichloro-benz-yl)pyridinium cations and [Ni(dmit)(2)] anions (dmit = 2-sulfanyl-idene-1,3-dithiole-4,5-dithiol-ate). In the anion, the Ni(III) ion exhibits a square-planar coordination involving four S atoms from two dmit ligands. In the crystal, weak S⋯S [3.368†(2) and 3.482†(3)†à ], Ni⋯S [3.680†(2)†à ] and Cl⋯S [3.491†(2)†à ] inter-actions and C-H⋯S hydrogen bonds lead to a three-dimensional supra-molecular network.
