title: Bis(1-amino-4-methyl-pyridinium) bis-(1,2-dicyano-ethene-1,2-dithiol-ato-κS,S')nickelate(II).
abstract: The asymmetric unit of the title compound, (C(6)H(9)N(2))(2)[Ni(C(4)N(2)S(2))(2)], contains one half of an [Ni(mnt)(2)](2-) anion (mnt is maleonitrile-dithiol-ate or 1,2-dicyano-ethene-1,2-dithiol-ate) and one 1-amino-4-methyl-pyridinium cation. The Ni(II) atom is located on an inversion centre. In the crystal structure, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules.
