title: N-Phenyl-6-(1H-pyrazol-1-yl)pyridazin-3-amine.
abstract: The mol-ecule of title compound, C(13)H(11)N(5), is essentially planar (r.m.s. deviation = 0.0440 Å) and an intra-molecular C-H⋯N hydrogen bond generates an S(6) motif. In the crystal, mol-ecules are connected into chains by inter-molecular N-H⋯N and C-H⋯N hydrogen bonds. In addition, π-π stacking inter-actions are observed between the pyrazole and pyridazine rings [inter-planar distance = 3.6859 (10) Å].
