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

Abstract

In the title compound, C20H21N5O, an intramolecular O—H...N hydrogen bond forms between the –OH substituent of the phenol ring and the adjacent iminomethyl N atom, enclosing an S6 ring. The dihedral angles between the imidazole ring and the methylphenyl and phenol rings are 86.93 (14) and 88.00 (13)°, respectively, while that between the methylphenyl and phenol rings is 2.18 (12)°.
