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.
在标题化合物（C₄H₁₂N₂）[ZnCl₄]中，锌原子采取略微扭曲的四面体几何构型。在晶体中，二价阳离子和二价阴离子通过N—H⋯Cl和N—H⋯（Cl，Cl）氢键相互作用，形成在（010）方向扩展的层状网络。氢键网络不均衡，三个氯原子各自接受两个氢键，而一个氯原子不接受任何氢键：后者呈现出最短的Zn—Cl键长。研究的晶体被发现是一个倒反孪晶。
