(E)-N′-[(2-Hydroxy-1-naphthyl)methylene]benzohydrazide monohydrate

Abstract

In the title compound, C18H14N2O2·H2O, the dihedral angle between the benzene ring and the naphthalene system is 5.18 (10)°. Intramolecular N—H...O hydrogen bonds influence the molecular conformation. In the crystal, intermolecular N—H...O and O—H...O hydrogen bonds are observed as well as π–π interactions between the phenyl ring and the substituted ring of the naphthalene [centroid–centroid distance = 3.676 (11) Å].
