Abstract

The title compound, [ZnCl₂(C₁₃H₁₁N₃)]·C₃H₇NO, crystallized in the monoclinic crystal system in space group P2₁/n. The asymmetric unit contains one neutral complex mol-ecule, which consists of a zinc ion, a bidentate ligand, and two chlorido ligands with di-methyl-formamide monosolvate. The ligand has two moieties, a benzimidazole and an aniline group. The benzimidazole and aniline planes are not coplanar, subtending a dihedral angle of 18.24 (8)°. The Zn(II) ion shows distorted tetra-hedral geometry, being coordinated by an imidazole N atom, the aniline N atom, and two chlorido ligands. The packing features N-H⋯O, N-H⋯Cl, C-H⋯Cl hydrogen bonding.

Keywords: aniline; benzimidazole; bidentate ligand; crystal structure; heterocyclic; zinc(II) complex.
