title: (E)-N'-[3-(4-Chloro-benzo-yloxy)benzyl-idene]pyridine-4-carbohydrazide acetic acid monosolvate monohydrate.
abstract: In the Schiff base mol-ecule of the title compound, C(20)H(14)ClN(3)O(3)·CH(3)COOH·H(2)O, the central benzene ring makes dihedral angles of 36.26 (7) and 27.59 (8)°, respectively, with the terminal chloro-phenyl and pyridine rings. In the crystal, the three components are linked by O-H⋯O, N-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds into a double-tape structure along the a axis.
