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.
标题离子对化合物(C₇H₇N₂)₂[Cu(C₄N₂S₂)₂]是通过氯化铜·二水合物(CuCl₂·2H₂O)、马来腈二硫醇二钠(Na₂mnt)和4-氰基-1-甲基吡啶碘化物直接反应制得的。阴离子和一个吡啶鎓阳离子完全位于一个镜面平面上,而对于另一个阳离子,一个晶体学镜面平面穿过吡啶环的N和对位C原子、甲基C原子以及氰基。在晶体中,离子通过C—H⋯N氢键连接成三维网络。
