In the title compound, C 14 H 9 BrN 2 O 2 , the whole molecule is roughly planar, the largest deviation from the mean plane being 0.159 (6) A ˚for the phenol O atom. The occurrence of an intramolecular O-HÁ Á ÁN hydrogen bond might favour this planar conformation. The packing is governed by weakinte

In the approximately planar molecule of the title compound, C 16 H 11 BrO 3 , the dihedral angle between the two benzene rings is 6.61 (18) . This compound crystallizes in a centrosymmetric space group, so it does not display a second-harmonic generation response.
