4-Allyl-2-[1-(5-allyl-2-hydroxy-3-methoxybenzyl)-1 H-benzimidazol-2-yl]-6-methoxyphenol pyridine solvate.

The title compound, C28H28N2O4·C5H5N, crystallizes with two molecules in the asymmetric unit. In both molecules, the benzimidazole ring system is essentially planar and forms dihedral angles of 85.35 (5) and 50.51 (5)° with the two benzene rings in one molecule, and 82.93 (5) and 51.30 (5)° in the other molecule. The hydroxy groups are coplanar with the attached benzene rings, whereas the methoxy groups are slightly twisted away from the planes of the attached benzene rings. O—H...O intramolecular hydrogen bonds involving the hydroxy and methoxy groups generate S(6) ring motifs. In the crystal structure, molecules are linked into chains along the [110] direction by O—H...N and C—H...O hydrogen bonds. [ABSTRACT FROM AUTHOR]
