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.
