2-{(E)-[(4-Anilinophenyl)imino]methyl}-4-[(E)-(4-methoxyphenyl)diazenyl]phenol

Abstract

In the title Schiff base compound, C26H22N4O2, the hydroxy group forms a intramolecular hydrogen bond to the imine N atom and generates anS(6) ring motif. The conformation about the C=N and N=N bonds isE. The 4-methoxybenzene ring and thep-phenylenediamine ring are inclined to the phenol ring by 11.61 (17) and 46.04 (17)°, respectively. The terminalN-phenyl ring is inclined to thep-phenylenediamine ring by 50.72 (17)°. In the crystal, adjacent molecules are linked by C—H...O hydrogen bonds, involving thep-phenylenediamine ring and the phenol ring, forming chains along [001]. The chains are linked by a number of C—H...π interactions, forming slabs propagating parallel to (100).
