Abstract: 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) . ?-? 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) ] link the hydrogen-bonded chains into layers parallel to (110). Weak C-H?F and C-H?O interactions further consolidate the crystal packing.
