title: (E)-N'-(5-Chloro-2-hydroxy-benzyl-idene)-3,5-dihydroxy-benzohydrazide mono-hydrate.
abstract: In the title compound, C(14)H(11)ClN(2)O(4)·H(2)O, the dihedral angle between the two benzene rings is 8.5 (2)° and an intra-molecular O-H⋯N hydrogen bond is observed in the Schiff base mol-ecule. In the crystal structure, the water mol-ecule accepts an N-H⋯O hydrogen bond and makes O-H⋯O hydrogen bonds to two further Schiff base mol-ecules. Further inter-molecular O-H⋯O hydrogen bonds lead to the formation of layers parallel to the bc plane.
