In the title compound, (C7H11N2)2[ZnCl4], [ZnCl4]2- anions and 4-(dimethylamino)pyridinium cations are held together by various intermolecular interactions including Coulombic attraction, hydrogen bonding and - stacking interactions. Three Cl atoms of the [ZnCl4]2- tetrahedron act as acceptors in N-HCl hydrogen bonds. The hydrogen bonds, both of which are bifurcated, lead to the formation of a three-dimensional network. Within the network, intermolecular - stacking interactions with a centroid-centroid distance of 3.5911 (7) Å arrange the 4-(dimethylamino)pyridinium cations into antiparallel dimers.
