1-(4-Methylphenylsulfonyl)-2-{[3-methyl-4-(2,2,2-trifluoroethoxy)pyridin-2-yl]methylsulfanyl}-1H-1,3-benzimidazole

Abstract

In the title compound, C23H20F3N3O3S2, the benzoimidazole unit makes dihedral angles of 5.02 (1) and 76.42 (1)°, respectively, with the pyridine and methylbenzene rings; the dihedral angle between the pyridine and methylbenzene rings is 72.19 (1)°. In the crystal, molecules are connected by weak C—H...F, C—H...O and C—H...N hydrogen bonds. Weak C—H...π interactions and π–π stacking [centroid–centroid distance = 3.6485 (14) Å] are also observed. The overall packing shows a three-dimensional architecture. The crystal structure contains a void of 51 Å3, but no solvent molecule (hexane or ethyl acetate) is located within it.
