Except two F atoms of the -CF(3) group, the title compound, C(14)H(8)BrF(3)N(2)O(3), has an almost planar conformation, the dihedral angle between the aromatic rings being 3.60 (16)°. The mol-ecule adopts the enol-imine tautomeric form, with an intra-molecular O-H⋯N hydrogen bond, which generates an S(6) ring motif. In the crystal, face-to-face π-π stacking [centroid-centroid distances = 3.669 (2) and 3.732 (2) Å] between the aromatic rings of the mol-ecules, which lie in sheets parallel to (202), help to establish the packing.
