Abstract: In the title complex, [ZnCl2(C10H9N5)2], the ZnII ion is coordinated by two N atoms from two 2-[(1H-1,2,4-triazol-1-yl)methyl]-1H-benzimidazole (tmb) ligands and by two chloride ligands in a slightly distorted tetrahedral 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 molecules into chains along [010]. In addition, weak C-H...Cl and C-H...N hydrogen bonds complete a three-dimensional network. Two weak intramolecular C-H...Cl hydrogen bonds are also observed.
