ABSTRACT: The asymmetric unit of the title compound, C15H13N3O7·2H2O, consists of a hydrazone molecule and two solvent water molecules. The molecule adopts an E configuration with respect to the C=N bond. It is relatively planar, with a dihedral angle between the two benzene rings of 2.6 (1)°. There are intramolecular O—H...N and O—H...O hydrogen bonds in the hydrazone molecule. In the crystal structure, symmetry-related molecules are linked through intermolecular N—H...O and O—H...O hydrogen bonds to form a three-dimensional network.
