The benzohydrazide molecule in the title dihydrate, C14H11ClN2O5·2H2O, is non-planar, with the two aromatic rings at either side of the –C(=O)—NH—N=CH– unit forming a dihedral angle of 29.7 (2)°. The benzohydrazide molecule is linked to the water molecules by O—H⋯O and N—H⋯O hydrogen bonds, with other O—H⋯O hydrogen bonds leading to a layer structure.

5-Chloro-2-hydroxybenzaldehyde (0.31 g, 2 mmol) and 3,4,5-trihydroxybenzoylhydrazide (0.36 g, 2 mmol) were heated in ethanol (50 ml) for several hours. The solvent was removed and the product recrystallized from DMSO.
Carbon-bound H-atoms were placed in calculated positions [C—H 0.95 Å, U(H) = 1.2U(C)], and were included in the
in the riding model approximation. The amino (0.88 Å) and hydroxy H-atoms (0.84 Å) were similarly generated with Uiso = 1.2Ueq(carrier atom) for N-H and Uiso = 1.5Ueq(carrier atom) for O-H. The water H-atoms were placed in chemically sensible positions on the basis of possible hydrogen bonds, but were not refined; Uiso = 1.5Ueq(O).Data collection: APEX2 (Bruker, 2008); cell
