Abstract: In the title compound, C₃₅H₂₄Cl₂N₄O, 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-HN, C-HO and C-HCl interactions. One of the C-HN interactions generates an R₂²(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-HN and C-HCl 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].
