title: 2-(Thio-phen-2-yl)-1-(thio-phen-2-ylmeth-yl)-1H-benzimidazole.
abstract: In the title compound, C(16)H(12)N(2)S(2), the thio-phene groups are rotationally disordered over two sets of sites, by approximately 180°, with occupancy ratios of 0.916 (2):0.084 (2) and 0.903 (2):0.097 (2). The major components of the thio-phene and methyl-ene substituted thio-phene rings are canted by 24.06 (12) and 85.07 (10)°, respectively, from the benzimidazole ring system plane and the dihedral angle between the major component thio-phene ring planes is 84.90 (14)°. In the crystal, there is a weak C-H⋯N hydrogen bond which links mol-ecules into chains.
