Bis(1-amino-4-methylpyridinium) bis(1,2-dicyanoethene-1,2-dithiolato-κ2S,S′)nickelate(II)

Abstract

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.
