Abstract

In the title compound, (C(4)H(12)N(2))[ZnCl(4)], the Zn atom adopts a slightly distorted tetra-hedral geometry. In the crystal, the dication and dianion inter-act by way of N-H⋯Cl and N-H⋯(Cl,Cl) hydrogen bonds to result in a layered network propagating in (010). The hydrogen-bonding network is unbalanced, with three Cl atoms accepting two hydrogen bonds each and one Cl atom not accepting any hydrogen bonds: the latter shows the shortest Zn-Cl bond length. The crystal studied was found to be an inversion twin.
