The asymmetric unit of the title salt, (C7H11N2)2[CuCl4], comprises half a tetrahedral tetra-chlorido-cuprate anion, being located on a twofold axis, and a protonated 4-(di-methyl-amino)-pyridine cation. The geometry around the Cu(II) ion is highly distorted with the range of Cl-Cu-Cl angles being 94.94 (1)-141.03 (1)°. The crystal structure is stabilized by N-H⋯Cl and C-H⋯Cl hydrogen bonds. In the three-dimensional network, cations and anions pack in the lattice so as to generate chains of CuCl4 anions separated by two orientations of cation layers, which are inter-locked through π-π stacking contacts between pairs of pyridine rings, with centroid-centroid distances of 3.7874 (7) Å.
标题盐（C₇H₁₁N₂）₂[CuCl₄]的不对称单元包含位于二重轴上的半个四面体四氯合铜酸根阴离子和一个质子化的4-（二甲基氨基）吡啶阳离子。Cu（II）离子周围的几何构型严重扭曲，Cl-Cu-Cl角的范围为94.94 (1)-141.03 (1)°。晶体结构通过N-H⋯Cl和C-H⋯Cl氢键得以稳定。在三维网络中，阳离子和阴离子堆积在晶格中，形成由阳离子层的两种取向隔开的[CuCl₄]²⁻阴离子链，这些阳离子层通过吡啶环对之间的π-π堆积接触相互锁定，质心间距为3.7874 (7) Å。
