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

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)degrees, and the dihedral angle between the hydroxyphenyl and benzimidazole rings in the other moiety is 14.83 (9)degrees. These angles are probably limited to small values as a consequence of two strong intramolecular O-H center dot center dot center dot 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)degrees.
