Abstract: In the title compound, C₁₀H₉N₅, the phenyl ring is twisted with respect to the pyrazole ring, forming a dihedral angle of 24.00 (6)°. In the crystal, molecules are linked by N-HN hydrogen bonds into chains running parallel to [010] containing alternating R₂²(6) and R₂²(12) rings. Further interactions are found in the crystal, viz. N-H(phenyl) interactions and weak face-to-face - stacking interactions [centroid-centroid distance = 3.8890 (6) Å] between the centroids of the pyrazole and phenyl rings are observed.
