| Summary: | The asymmetric unit of the title compound, (C13H11Cl2N2)2[Ni(C4N2S2)2], contains one-half of a centrosymmetric [Ni(mnt)2] anion (where mnt is maleonitriledithiolate or 1,2-dicyano-1,2-ethylenedithiolate) and an (E)-1-(3,4-dichlorobenzylideneamino)-4-methylpyridinium cation. In the anion, the coordination around the Ni atom is a distorted square. In the cation, the aromatic rings are oriented at a dihedral angle of 7.81 (3)°. In the crystal structure, intermolecular C—H...N hydrogen bonds link the cations and anions. π–π Contacts between the nickel dithiolene and pyridine rings and between the benzene and pyridine rings, [centroid–centroid distances = 3.682 (3) and 3.643 (3) Å, respectively] may further stabilize the structure.
