چکیده
In the title compound, C(16)H(15)ClN(2)O(3)·H(2)O, the water mol-ecule is linked to the Schiff base mol-ecule via an O-H⋯O hydrogen bond. In the Schiff base mol-ecule, 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 mol-ecules are linked by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, forming layers in the ab plane.
