2-{(E)-[4-(Diphenylamino)phenyl]iminomethyl}phenol

Abstract

The asymmetric unit of the title Schiff base molecule, C25H20N2O, contains two independent molecules. In each molecule, the C=N bond is in an E conformation. The most significant difference between the two molecules is seen for the dihedral angles between the methoxy-substituted benzene ring and the two phenyl rings, which are 85.5 (1) and 82.3 (1)° in the first molecule, and 49.0 (1) and 40.4 (1)° in the second. This conformational difference is reflected in the central C=N—C...;C torsion angle, which is 28.7 (2)° in the first molecule and −29.8 (3)° in the other. In each molecule, there is an intramolecular O—H...N hydrogen bond.
