Crystal structure of 1-[(2,2-dimethyl-1,3-dioxolan-4-yl)methyl]-2-(thiazol-4-yl)-1H-benzimidazole
Abstract
The benzimidazole ring in the title compound, C16H17N3O2S, is almost planar, with the greatest deviation from the mean plane being 0.032 (1) Å. The fused-ring system makes dihedral angles of 19.91 (7) and 24.51 (8)° with the best plane through each of the thiazol-4-yl and 1,3-dioxolan-4-yl rings, respectively; the latter exhibits an envelope conformation with the methylene C atom being the flap. Finally, the thiazol-4-yl ring makes a dihedral angle of 33.85 (9)° with the 1,3-dioxolan-4-yl ring. In the crystal, molecules are connected by a pair of C—H...π(imidazole) interactions to form centrosymmetric aggregates.
