title: 2-(1H-1,3-Benzodiazol-2-ylsulfan-yl)-1-(4-chloro-phen-yl)ethanone.
abstract: The mol-ecule in the structure of the title compound, C(15)H(11)ClN(2)OS, displays two planar residues [r.m.s. deviation = 0.014 Å for the benzimidazole residue, and the ketone group is co-planar with the benzene ring to which it is attached forming a O-C-C-C torsion angle of -173.18 (14) °] linked at the S atom. The overall shape is based on a twisted V, the dihedral angle formed between the two planes being 82.4 (2) °. The amine-H atom is bifurcated, forming N-H⋯O and N-H⋯S hydrogen bonds leading to dimeric aggregates. These are linked into a supra-molecular chain along the c axis via C-H⋯π hydrogen bonds. Chains form layers in the ab plane being connected along the c axis via weak π-π inter-actions [3.9578 (8) Å] formed between centrosymmetrically related chloro-substituted benzene rings.
