Abstract: In the crystal structure of the title compound, C13H7N3O·H2O, the components are associated into chains along  through strong O-HO hydrogen bonds with the free water molecules as bridging ligands. These chains are further cross-linked by C-HO and C-HN hydrogen bonds, forming a three-dimensional structure.
