Bis[4-(dimethyl-amino)-pyridinium] tetra-chloridozincate.

ABSTRACT: In the title compound, (C(7)H(11)N(2))(2)[ZnCl(4)], [ZnCl(4)](2-) anions and 4-(dimethyl-amino)-pyridinium cations are held together by various inter-molecular inter-actions including Coulombic attraction, hydrogen bonding and ?-? stacking inter-actions. Three Cl atoms of the [ZnCl(4)](2-) tetra-hedron act as acceptors in N-H?Cl hydrogen bonds. The hydrogen bonds, both of which are bifurcated, lead to the formation of a three-dimensional network. Within the network, inter-molecular ?-? stacking inter-actions with a centroid-centroid distance of 3.5911?(7)?Å arrange the 4-(dimethyl-amino)-pyridinium cations into anti-parallel dimers.

In the title compound, (C(7)H(11)N(2))(2)[ZnCl(4)], [ZnCl(4)](2-) anions and 4-(dimethyl-amino)-pyridinium cations are held together by various inter-molecular inter-actions including Coulombic attraction, hydrogen bonding and π-π stacking inter-actions. Three Cl atoms of the [ZnCl(4)](2-) tetra-hedron act as acceptors in N-H⋯Cl hydrogen bonds. The hydrogen bonds, both of which are bifurcated, lead to the formation of a three-dimensional network.
