2-{2-[4-(Dimethyl-amino)-phen-yl]diazen-1-ium-1-yl}pyridinium tetra-chlorido-zincate.

ABSTRACT: The title compound, (C(13)H(16)N(4))[ZnCl(4)], consists of a tetra-hedral [ZnCl(4)](2-) anion and a 2-{2-[4-(dimethyl-amino)-phen-yl]diazen-1-ium-1-yl}pyridinium dication. The pyridinium-N atom is syn to the azo bond which allows for the formation of an intramolecular N-H?N hydrogen bond. In the crystal, the cation and anion are held together by N-H?Cl hydrogen-bond inter-actions involving the pyridinium and diazen-1-ium N atoms. ?-? stacking inter-actions occur between the pyridine and benzene rings of adjacent cations [centroid-centroid distances = 3.6270?(18) and 3.8685?(18)?Å]; the stacks are parallel to the a axis.
