5-Amino-3-anilino-1H-pyrazole-4-carbonitrile

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—H...N 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...π(phenyl) interactions and weak face-to-face π–π stacking interactions [centroid–centroid distance = 3.8890 (6) Å] between the centroids of the pyrazole and phenyl rings are observed.
