The title compound, C18H13F2NO2, is a polymorph of the structure reported by Sunitha et al. [Acta Cryst. (2015), E71, o341–o342]. Both compounds crystallize in the triclinic space group P-1. The principal difference between the two polymorphs lies in the orientation of the carboxyl­ate substituents with respect to the planes of the quinoline ring systems. In the crystal, the packing features C—H⋯O hydrogen bonds together with short C—F⋯π and π–π inter­actions.
