The whole mol-ecule of the title compound, [NiCl2(C3H4N2)2(NH3)2], is generated by inversion symmetry. The Ni(II) ion, which is located on an inversion center, has a distorted octa-hedral coordination environment and is surrounded by two ammine N atoms and two Cl atoms in the equatorial plane, with two N atoms of two imidazole groups occupying the axial positions. The imidazole ring makes a dihedral angle of 81.78 (18)° with the Ni/N/Cl equatorial plane. In the crystal, mol-ecules are linked via N-H⋯Cl hydrogen bonds and C-H⋯π inter-actions, forming a three-dimensional network.
标题化合物[NiCl₂(C₃H₄N₂)₂(NH₃)₂]的整个分子由反演对称性生成。位于反演中心的Ni(II)离子具有扭曲的八面体配位环境，在赤道平面上被两个氨N原子和两个Cl原子包围，两个咪唑基团的两个N原子占据轴向位置。咪唑环与Ni/N/Cl赤道平面的二面角为81.78 (18)°。在晶体中，分子通过N—H⋯Cl氢键和C—H⋯π相互作用相连，形成三维网络。
