title: Bis[1-(4-cyano-benz-yl)pyrazinium] bis-(1,2-dicyano-ethene-1,2-dithiol-ato)nickelate(II).
abstract: The asymmetric unit of the title complex, (C(12)H(10)N(3))(2)[Ni(C(4)N(2)S(2))(2)], consists of one 1-(4-cyano-benz-yl)pyrazinium cation and one half of an [Ni(mnt)(2)](2-) dianion (mnt(2-) is 1,2-dicyano-ethene-1,2-dithiol-ate). The Ni(2+) ion is located on an inversion center and is coordinated by four S atoms from two mnt(2-) ligands, exhibiting a square-planar coordination geometry. The cation adopts a conformation where both the pyrazine ring and the benzene ring are twisted with respect to the C-C-N reference plane by 16.5 (2) and 69.8 (1)°, respectively.
