Abstract :
The molecule of the title compound, C28H22N4O9, exhibits crystallographically imposed twofold rotational symmetry, with a dihedral angle of 66.0 (2)° between the planes of the two central benzene rings bounded to the central oxygen atom. The dihedral angle between the planes of the central benzene ring and the terminal phenol ring is 4.9 (2)°. Each half of the molecule exhibits an imine E configuration. An intramolecular O—H⋯N hydrogen bond is present. In the crystal, the molecules are linked into layers parallel to the ab plane via C—H⋯O hydrogen bonds. The crystal studied was refined as a two-component pseudomerohedral twin.
