2-(Thiophen-2-yl)-1-(thiophen-2-ylmethyl)-1H-benzimidazole

Abstract

In the title compound, C 16H 12N 2S 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 thiophene and methylene substituted thiophene 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 thiophene ring planes is 84.90 (14)°. In the crystal, there is a weak C - H⋯N hydrogen bond which links molecules into chains.
