title: (E)-3-[(4-Diethyl-amino-2-hydroxy-benzyl-idene)amino]benzonitrile.
abstract: The mol-ecule of the title compound, C(18)H(19)N(3)O, displays a trans configuration with respect to the C=N double bond. There is a strong intra-molecular O-H⋯N hydrogen-bonding inter-action between the hydr-oxy group and imine N atom. The dihedral angle between the aromatic rings is 30.35 (8)°. The crystal packing is stabilized by O-H⋯N links.
