2-((E)-{[3-(1H-Imidazol-1-yl)propyl]imino}methyl)-4-[(E)-(4-methylphenyl)diazenyl]phenol

Abstract

In the title compound, C20H21N5O, the dihedral angles between the central phenol ring and pendant toluyl and imidazole rings are 3.20 (16) and 81.44 (14)°, respectively; the dihedral angle between the pendant rings is 84.39 (16)°. An intramolecular O—H...N hydrogen bond occurs. A Hirshfeld fingerprint analysis indicates that H...H contacts account for 48.6% of the surface.
