Abstract: There are two independent formula units in the asymmetric unit of the title compound, C15H13N3O4·H2O. The C=C-N-C torsion angle of the methylidenehydrazide group is 174.3 (2)° in one molecule and 178.6 (2)° in the other. The dihedral angles between the two benzene rings in the two molecules are 4.17 (12) and 3.58 (12)°. In the crystal structure, intermolecular O-HO, N-HO and O-HN hydrogen bonds link the components into a two-dimensional network and additional stabilization is provided by weak intermolecular C-HO hydrogen bonds.
