Abstract: The asymmetric unit of the title compound, C₁₃H₁₀F₃NO₃, contains two independent molecules with similar conformations. In the crystal, N-HO 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)°. [pi] - [pi] 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-HF and C-HO interactions further consolidate the crystal packing.
