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.

The asymmetric unit of the title compound, (C6H9N2)2[Ni(C4N2S2)2], contains one half of an [Ni(mnt)2]2− anion (mnt is maleonitrile­dithiol­ate or 1,2-dicyano­ethene-1,2-dithiol­ate) and one 1-amino-4-methyl­pyridinium cation. The NiII atom is located on an inversion centre. In the crystal structure, inter­molecular N—H⋯N hydrogen bonds link the mol­ecules.
