In the title solvate, C44H30Cl2N2O2·2C4H8O2, the complete polycyclic mol-ecule is generated by inversion symmetry. The dihedral angle between the quinolyl ring system (Q; r.m.s. deviation = 0.020 Å) and the pendant phenyl ring is 78.80 (6)°; the dihedral angle between Q and the central benzene ring is 85.92 (7)°. In the crystal, the components are linked by C-H⋯O and C-H⋯π inter-actions, generating (110) layers. Weak aromatic π-π stacking [centroid-centroid distances = 3.7025 (11) and 3.8124 (10) Å] is also observed.
