3-Chloro-N′-(3-ethoxy-2-hydroxybenzylidene)benzohydrazide monohydrate

Abstract

In the title compound, C16H15ClN2O3·H2O, the water molecule is linked to the Schiff base molecule via an O—H...O hydrogen bond. In the Schiff base molecule, an intramolecular O—H...N hydrogen bond occurs and the dihedral angle between the two benzene rings is 20.5 (5)°. In the crystal, the Schiff base and water molecules are linked by intermolecular N—H...O and O—H...O hydrogen bonds, forming layers in the ab plane.
