In the title compound, C(20)H(14)Cl(2)F(3)NO(3), the trifluromethyl group is disordered over two sets of sites in a 0.784 (10):0.216 (10) ratio. The quinoline ring system is essentially planar with a maximum deviation of 0.058 (2) Å for the N atom and forms dihedral angles of 89.23 (11) and 8.13 (17)°, respectively with the mean planes of the benzene ring and the carboxyl-ate group. In the crystal, pairs of weak C-H⋯O and C-H⋯F hydrogen bonds link mol-ecules into centrosymmetric dimers. The crystal structure is further stabilized by weak π-π [centroid-centroid distance = 3.624 (2) Å] inter-actions.
