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 ZnII 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].
