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

Abstract

In the title compound, C29H25N3O 3, 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)°.
