2-[1-(3-{2-[(2-Hy­droxy­benzyl­idene)amino]­phen­oxy}prop­yl)-1H-1,3-benzodiazol-2-yl]phenol

Abstract

In the title compound, C29H25N3O3, the imine double bond has an E configuration. The dihedral angle between the hy­droxy­phenyl and benzene rings in the imine moiety is 26.95 (9)°, and the dihedral angle between the hy­droxy­phenyl and benzimidazole rings in the other moiety is 14.83 (9)°. These angles are probably limited to small values as a consequence of two strong intra­molecular O—H⋯N hydrogen bonds formed between the hy­droxy groups and the imine and imidazole N atoms. The aliphatic chain linking the two ring systems has a gauche conformation, as reflected in C—C—C—O torsion angle of 70.9 (2)°
