Diethyl 7,7′-dichloro-4-oxo-4H-[1,4′-biquinoline]-3,3′-dicarboxylate

Diethyl 7,7′-dichloro-4-oxo-4H-[1,4′-biquinoline]-3,3′-dicarboxylate

In the title compound, C24H18Cl2N2O5, the quinoline and quinolinone moieties are nearly perpendicular to each other, forming a dihedral angle of 82.36 (3)°. In the crystal, molecules form a halogen bond between a Cl atom of a quinolinone moiety and the N atom of the quinoline moiety of the inversion...
