Abstract: In the molecule of the title compound, C₁₇H₈Cl₂F₈N₂O₃, the two aromatic rings are oriented at a dihedral angle of 50.12 (3)°. Intramolecular N-HO, C-HO and N-HCl hydrogen bonds result in the formation of two six- and one five-membered rings. The six-membered rings have flattened-boat conformations, while the five-membered ring adopts an envelope conformation. In the crystal structure, intermolecular N-HO hydrogen bonds link the molecules into centrosymmetric dimers.
