N,N,N′,N′-Tetra­methyl­ethylene­diammonium tetra­chlorido­zincate

The asymmetric unit of the title compound, (C₆H₁₈N₂)[ZnCl₄], consists of one tetra­chlorido­zincate anion and two half-N,N,N′N′-tetra­methyl­ethylenedi­ammonium cations. Each of the two di­ammonium cations is located about an inversion center and one of them is disordered over two sets of sites in a 0.780 (17):0.220 (17) ratio. The Zn^II atom has a slightly distorted tetra­hedral coordination environment. The cations and anions are connected via N—H...Cl hydrogen bonds into chains extending along [0-11].
