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, mol-ecules form a halogen bond between a Cl atom of a quinolinone moiety and the N atom of the quinoline moiety of the inversion equivalent [Cl⋯N = 3.106 (3) Å]. The mol-ecules also form two kinds of C-H⋯O hydrogen-bonded centrosymmetric inversion dimers, making chains along the c-axis direction which are further inter-linked by the halogen bonds into layers parallel to the bc plane.
在标题化合物C₂₄H₁₈Cl₂N₂O₅中，喹啉和喹啉酮部分几乎相互垂直，形成的二面角为82.36 (3)°。在晶体中，分子在喹啉酮部分的一个Cl原子与反演等效的喹啉部分的N原子之间形成卤键[Cl⋯N = 3.106 (3) Å]。分子还形成两种C—H⋯O氢键连接的中心对称反演二聚体，沿c轴方向形成链，这些链通过卤键进一步相互连接形成平行于bc平面的层。
