In the title compound, C21H12N4O·H2O, the five-membered ring is essentially planar with a maximum deviation of 0.004 (2) Å. An N - H⋯O hydrogen bond connects the organic and water molecules. In the crystal, O - H⋯N hydrogen bonds link molecules into a two-dimensional network parallel to (100). Hirshfeld surface analyses and two-dimensional fingerprint plots were used to quantify the intermolecular interactions present in the crystal, indicating that the most important contributions for the crystal packing are from H⋯H (28.7%), C⋯H/H⋯C (27.1%), N⋯H/H⋯N (26.4%), C⋯N/N⋯C (6.1%), O⋯H/H⋯O (3.7%) and C⋯C (6.0%) interactions.
