Abstract: In the title compound, C₁₁H₉N₅O, the pyrazolopyrimidin-4-one ring system is almost planar, with a maximum deviation of 0.0546 (13) Å for the O atom. The crystal packing is stabilized by intermolecular N-HN, C-HO and C-HN hydrogen bonds. In addition, - stacking is found between the pyridine ring and the pyrazolopyrimidin-4-one ring systems, with centroid-centroid distances in the range 3.9627 (12)-4.6781 (12) Å.
