In the title compound, C29H27ClN4O 2, the six-membered ring of the pyridazine group is nearly planar [maximum deviation = -0.062 (2) Å] and its mean plane makes dihedral angles of 43.05 (9), 44.71 (10) and 72.57 (9)°, respectively, with the two phenyl and benzene rings. The piperazine ring has a chair conformation and its mean plane is almost perpendicular to the attached benzene ring, with a dihedral angle of 83.20 (16)°. In the crystal, molecules are linked via two pairs of C - H⋯O interactions, which result in the formation of chains propagating along [101̄]. Neighbouring chains are linked via C - H⋯π interactions.
