In the title complex, [ZnCl2(C10H9N5)2], the Zn(II) ion is coordinated by two N atoms from two 2-[(1H-1,2,4-triazol-1-yl)meth-yl]-1H-benzimidazole (tmb) ligands and by two chloride ligands in a slightly distorted tetra-hedral geometry. In the tmb ligands, the benzimidazole rings systems are essentially planar, with maximum deviations from the mean plane of 0.021 (3) and 0.030 (3) Å, and form dihedral angles of 73.2 (2) and 83.5 (2)° with the triazole rings. In the crystal, N-H⋯N hydrogen bonds link complex mol-ecules into chains along [010]. In addition, weak C-H⋯Cl and C-H⋯N hydrogen bonds complete a three-dimensional network. Two weak intra-molecular C-H⋯Cl hydrogen bonds are also observed.
在标题配合物[ZnCl₂(C₁₀H₉N₅)₂]中，Zn(II)离子由来自两个2-[(1H-1,2,4-三唑-1-基)甲基]-1H-苯并咪唑(tmb)配体的两个N原子以及两个氯配体配位，呈略微扭曲的四面体几何构型。在tmb配体中，苯并咪唑环体系基本呈平面状，与平均平面的最大偏差为0.021(3)和0.030(3) Å，并且与三唑环形成的二面角为73.2(2)和83.5(2)°。在晶体中，N-H⋯N氢键将配合物分子沿[010]连接成链。此外，弱C-H⋯Cl和C-H⋯N氢键构成了三维网络。还观察到两个弱分子内C-H⋯Cl氢键。
