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)degrees. In the crystal, molecules are linked by N-H center dot center dot center dot N hydrogen bonds into chains running parallel to [010] containing alternating R-2(2)(6) and R-2(2)(12) rings. Further interactions are found in the crystal, viz. N-H center dot center dot center dot pi (phenyl) interactions and weak face-to-face pi-pi stacking interactions [centroid-centroid distance = 3.8890 (6) angstrom] between the centroids of the pyrazole and phenyl rings are observed.
