catena-Poly[(chloridozinc)-μ-5-(1-methyl-1H-benzimidazol-2-yl-κN (3))-1,2,3-triazol-1-ido-κ(2) N (1):N (3)]

In the title complex, [Zn(C(10)H(8)N(5))Cl](n), the Zn(II) ion is four-coordinated by one Cl atom and three N atoms from two in situ-generated deprotonated 5-(1-methyl-1H-benzimidazol-2-yl-κN (3))-1,2,3-triazol-1-ide ligands in a slightly distorted tetra­hedral geometry. The Zn(II) ions are bridged by the ligands, forming a helical chain along [001]. C—H⋯N and C—H⋯Cl hydrogen bonds and π–π inter­actions between the imidazole rings [centroid–centroid distance = 3.4244 (10) Å] assemble the chains into a three-dimensional supra­molecular network.
