1-[4-(4-Chloro­phen­yl)piperazin-1-yl]-3-(6-oxo-3,4-di­phenyl-1,6-di­hydro­pyridazin-1-yl)propan-1-one

Abstract

In the title compound, C29H27ClN4O2, the six-membered ring of the pyridazine group is nearly planar [maximum deviation = -0.062 (2) angstrom] and its mean plane makes dihedral angles of 43.05 (9), 44.71 (10) and 72.57 (9)degrees, 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)degrees. In the crystal, molecules are linked via two pairs of C-H center dot center dot center dot O interactions, which result in the formation of chains propagating along [10 (1) over bar]. Neighbouring chains are linked via C-H center dot center dot center dot pi interactions.
