Except two F atoms of the -CF3 group, the title compound, C14H8BrF3N2O3, has an almost planar conformation, the dihedral angle between the aromatic rings being 3.60 (16)degrees. The molecule adopts the enol-imine tautomeric form, with an intramolecular O-H center dot center dot center dot N hydrogen bond, which generates an S(6) ring motif. In the crystal, face-to-face pi-pi stacking [centroid-centroid distances = 3.669 (2) and 3.732 (2) angstrom] between the aromatic rings of the molecules, which lie in sheets parallel to (202), help to establish the packing.
