Abstract:
In the title compound, C(15)H(13)BrN(2)O(2), the two aromatic rings form a dihedral angle of 7.9 (1)° and an intra-molecular N-H⋯O hydrogen bond influences the mol-ecular conformation. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains propagated in [001]. The crystal packing exhibits also π-π inter-actions, which pair mol-ecules into centrosymmetric dimers with short inter-molecular distances of 3.671 (4) Å between the centroids of aromatic rings.
