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.

Summary
Benzimidazoles as organic ligands have attracted interest with regard to the synthesis of metal–organic frameworks, because of their coordination abilities to metal ions, and their significant potential applications in biological systems (Ahmad & Bharadwaj; 2013; Sharma et al, 2016; Gu et al, 2017). Benzimidazole compounds and their metal complexes have been found to show diverse biological activity (Podunavac-Kuzmanovic & Cvetkovic, 2010), including inhibition against enteroviruses (Xue et al, 2011) and potent antitumor activity (Galarce et al, 2008).
