Crystal structure and Hirshfeld surface analysis of 4-(2,6-di-chloro-benz-yl)-6-phenyl-pyridazin-3(2)-one.

The asymmetric unit of the title compound, CHClNO, contains one independent mol-ecule. The mol-ecule is not planar, the phenyl and pyridazine rings are twisted with respect to each other, making a dihedral angle of 29.96 (2)° and the di-chloro-phenyl ring is nearly perpendicular to the pyridazine ring, with a dihedral angle of 82.
