1-Ethenyl-4-[(phenylsulfanyl)methyl]­benzene

The dihedral angle between the aromatic rings in the title compound, C₁₅H₁₄S, is 72.38 (7)°. In the crystal, the mol­ecules are connected by C—H...π inter­actions.

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

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.
