3-Chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)pyridazine

Abstract

In the title compound, C9H9ClN4, the dihedral angle between the aromatic rings is 6.25 (9)°. The whole molecule is approximately planar (r.m.s. deviation = 0.070 Å). In the crystal, π–π interactions between the centroids of the pyridazine rings [separation = 3.5904 (10) Å] occur.
