Abstract
In the title compound, [ZnCl2(C14H12N2)2], the ZnII atom exhibits a distorted tetrahedral coordination geometry involving two chloride anions and two N-atom donors from 1-benzyl-1H-benzimidazole ligands. In both ligands, the benzyl and benzimidazole rings are nearly perpendicular [dihedral angles = 81.7 (2) and 81.5 (2)°]. The two benzimidazole systems are essentially planar [maximum deviations = 0.015 (3) and 0.020 (2) Å] and form a dihedral angle of 78.09 (8)°. In the crystal, centrosymmetrically related molecules are linked by pairs of C—H⋯Cl hydrogen bonds into chains parallel to the a axis.
