title: (E)-2-(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. The dihedral angle between the planes of the two benzene rings is 2.62 (11)°. A strong intra-molecular O-H⋯N hydrogen bond stabilizes the mol-ecular conformation.
