3-[1-(3-Hydroxybenzyl)-1H-benzimidazol-2-yl]phenol dimethyl sulfoxide monosolvate

Abstract

Crystals of the title compound were obtained as a 1:1 dimethyl sulfoxide solvate, C20H16N2O2·C2H6O. The molecular conformation of the organic molecule is similar to that in the previously reported unsolvated structure [Eltayeb et al. (2009). Acta Cryst. E65, o1374–o1375]. Thus, the dihedral angles formed by the benzimidazole moiety with the two benzene rings are 57.54 (4) and 76.22 (5)°, and the dihedral angle between the benzene rings is 89.23 (5)°. In the crystal, a three-dimensional network features O—H...O, O—H...N and O—H...S hydrogen bonds, as well as C—H...O and C—H...π interactions

Crystal structure and Hirshfeld surface analysis of a new benzimidazole compound, 3-{1-[(2-hydroxyphenyl)methyl]-1H-1,3-benzodiazol-2-yl}phenol

“…The benzimidazole moiety subtends dihedral angles of 46.16 (7) and 77.45 (8) � with the benzene rings, which themselves form a dihedral angle of 54.34 (9) � . These angles are in agreement with those observed in similar structures (Quezada-Miriel et al, 2012;Shu-Ping Yang et al, 2007).…”
