In the title compound, C23H19N5O6· H2O, the two components are linked into complex chains by a combination of two independent O—H⋯ O and two independent N—H⋯ O hydrogen bonds. The complex chains are linked into a two-dimensional sheet network via π– π stacking interactions and C—H⋯ O hydrogen bonds.
