5-Bromo-2-(phenyl-amino)-benzoic acid

Abstract

The title compound, C₁₃H₁₀BrNO₂, was obtained by the reaction of 2,5-di-bromo-benzoic acid and aniline. The mol-ecule is twisted with a dihedral angle between the aromatic rings of 45.74 (11)° and an intr-amolecular N-H⋯O hydrogen bond is seen. In the crystal, pairwise O-H⋯O hydrogen bonds generate carb-oxy-lic acid inversion dimers.

Keywords: acid-acid dimer; crystal structure; hydrogen bond; synthon.
