title: 3-Chloro-6-(1H-pyrazol-1-yl)pyridazine.
abstract: The title compound, C(7)H(5)ClN(4), is almost planar (r.m.s. deviation = 0.022 Å). The dihedral angle between the aromatic rings is 2.82 (5)°. The packing results in polymeric chains extending along the a axis. In the crystal, mol-ecules are connected to each other through inter-molecular C-H⋯N hydrogen bonds, resulting in R(2) (2)(10) ring motifs.
