摘要：

The asymmetric unit of the title salt, (C7H11N2)(2)[CuCl4], comprises half a tetrahedral tetrachloridocuprate anion, being located on a twofold axis, and a protonated 4-(dimethylamino)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 NH center dot center dot center dot Cl and C-H center dot center dot center dot Cl hydrogen bonds. In the threedimensional network, cations and anions pack in the lattice so as to generate chains of [CuCl4](2-) anions separated by two orientations of cation layers, which are interlocked through pi-pi stacking contacts between pairs of pyridine rings, with centroid-centroid distances of 3.7874 (7)
