| Summary: | In the title Schiff base compound, C26H22N4O2, the hydroxy group forms a intramolecular hydrogen bond to the imine N atom and generates an S(6) ring motif. The conformation about the C=N and N=N bonds is E. The 4-methoxybenzene ring and the p-phenylenediamine ring are inclined to the phenol ring by 11.61 (17) and 46.04 (17)°, respectively. The terminal N-phenyl ring is inclined to the p-phenylenediamine ring by 50.72 (17)°. In the crystal, adjacent molecules are linked by C—H...O hydrogen bonds, involving the p-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).
