The title compound, [Cu(C16H13N4O3)Cl], has been prepared by the reaction of 2-[(5-nitrosalicylidene)aminoethyl]-1H-benzimidazole, L, with copper(II) chloride. Ligand L coordinates to the central Cu atom through two N atoms and one O atom, and a chloride ligand completes a distorted square-planar environment at the CuII centre. The chloride ligand is trans to the central N atom of the N,N,O-tridentate ligand. There are substantial distortions from ideal geometry at the copper centre, with an O—Cu—N angle of 147.35 (11)° and an N—Cu—Cl angle of 134.89 (9)°. There are intermolecular N—H…Cl hydrogen bonds parallel to the a axis.
