(E)-4-[(4-Diethylamino-2-hydroxybenzylidene)amino]benzonitrile

Abstract

The title compound, C18H19N3O, displays an E conformation with respect to the C=N double bond. The dihedral angle between the mean planes of the two benzene rings is 24.49 (3)°. An intramolecular O—H...N hydrogen bond generates an S(6) ring. In the crystal, molecules are linked by nonclassical intermolecular C—H...O hydrogen bonds to form an infinite one-dimensional chain along [010], generating a C(8) motif.
