In the title hydroxamic acid derivate, C22H16Cl2N2O5, the nitro-substituted benzene ring forms dihedral angles of 14.11 (15) and 16.08 (15)°, with the 4-chloro-benzoyl and 4-chloro-phenyl benzene rings, respectively. The dihedral angle between the chloro-substituted benzene rings is 2.28 (13)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming chains along [100].
在标题异羟肟酸衍生物C22H16Cl2N2O5中,硝基取代的苯环与4-氯苯甲酰基苯环和4-氯苯基苯环分别形成14.11 (15)°和16.08 (15)°的二面角。氯取代苯环之间的二面角为2.28 (13)°。在晶体中,分子通过弱C—H⋯O氢键相连,沿[100]方向形成链状结构。
