چکیده
The asymmetric unit of the title compound, C(15)H(12)Br(2)N(2)O(2), contains two independent mol-ecules in which the dihedral angles between the benzene rings are 49.5 (7) and 66.4 (7)°. Intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs in each mol-ecule. In the crystal, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains along the b axis.
