چکیده
The title ion-pair compound, (C(7)H(7)N(2))(2)[Cu(C(4)N(2)S(2))(2)], was obtained by the direct reaction of CuCl(2)·2H(2)O, disodium maleonitrile-dithiol-ate (Na(2)mnt) and 4-cyano-1-methyl-pyridinium iodide. The anion and one pyridinium cation lie entirely on a mirror plane, whereas for the other cation, a crystallographic mirror plane runs through the N and para-C atoms of the pyridine ring, the methyl C atom, and the cyano group. In the crystal, ions are linked into a three-dimensional network by C-H⋯N hydrogen bonds.
