Abstract: There are two independent molecules in the asymmetric unit of the title compound, C16H11ClN2S2. The structure exhibits rotational disorder of the 2-thiophen-2-yl substituent in each of the unique molecules with a major:minor component ratio of 0.927 (2):0.073 (2). For one of the symmetry-unique molecules, 6.0 (2)% of the sites are occupied by the 6-chloro-isomer. The major component thiophene rings make dihedral angles of 38.90 (12) and 36.32 (11)° with the benzimidazole rings in the two independent molecules. In the crystal, molecules are linked into chains parallel to  via weak C-HN interactions.
