| Summary: | The asymmetric unit of the title compound, C13H10F3NO3, contains two independent molecules with similar conformations. In the crystal, N—H...O hydrogen bonds link alternating independent molecules into chains in [-110]. In the chain, the quinoline planes of the independent molecules are almost perpendicular to each other, forming a dihedral angle of 89.8 (1)°. π–π interactions between the aromatic rings of quinoline bicycles related by inversion centres [for two independent centrosymmetric dimers, the shortest centroid–centroid distances are 3.495 (1) and 3.603 (1) Å] link the hydrogen-bonded chains into layers parallel to (110). Weak C—H...F and C—H...O interactions further consolidate the crystal packing.
