Abstract

In the title mol­ecule, C9H6BrNO2, the dihedral angle between the –COOH group and the ring system is 6 (4)°. In the crystal, pairs of O—H⋯O hydrogen bonds link the mol­ecules into inversion dimers and these dimers are connected via N—H⋯O hydrogen bonds to form layers parallel to the (-101) plane.
