2,6-Bis(2-chloro­phen­yl)-4-oxo-3,5-diphenyl­heptane-1,1,7,7-tetra­carbo­nitrile

In the title compound, C(35)H(24)Cl(2)N(4)O, the phenyl rings are oriented almost parallel to each other, making a dihedral angle of 0.6 (2)°, whereas the chloro­phenyl rings are oriented at a dihedral angle of 28.3 (1)°. The crystal structure is stabilized through an extensive series of C—H⋯N, C—H⋯O and C—H⋯Cl inter­actions. One of the C—H⋯N inter­actions generates an R (2) (2)(12) ring motif around a crystallographic inversion centre. C(5), C(10) and C(12) chain motifs are observed in the unit cell through C—H⋯N and C—H⋯Cl inter­actions. During the structure analysis, it was observed that the unit cell contains large accessible voids, which host disordered solvent mol­ecules. This affects the diffraction pattern, mostly at low scattering angles and was corrected with the SQUEEZE program [Spek, A. L. (2009 ▶). Acta Cryst. D65, 148–155].
