title: 1-[(2-Anilinoeth-yl)iminiometh-yl]-2-naph-thol-ate.
abstract: The title Schiff base compound, C(19)H(18)N(2)O, was prepared by the reaction of equimolar quanti-ties of 2-hydr-oxy-1-naphthaldehyde with N-phenyl-ethane-1,2-diamine in a methanol solution. The mol-ecule adopts a zwitterionic conformation with the naphthyl OH group deprotonated and the imine N atom protonated. An intra-molecular N-H⋯O hydrogen bond forms between them. The dihedral angle between the benzene ring and the naphthyl system is 86.9 (2)°. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains running along the b axis.
