title: Dichloridobis{2-[(1H-1,2,4-triazol-1-yl)meth-yl]-1H-benzimidazole-κN (3)}-zinc(II).
abstract: 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.
