5-Chloro-2-(thio­phen-2-yl)-1-(thio­phen-2-ylmeth­yl)-1H-benzimidazole–6-chloro-2-(thiophen-2-yl)-1-(thiophen-2-ylmethyl)-1H-benzimidazole (0.94/0.06)

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 [100] via weak C—H...N inter­actions.
