چکیده
The title compound, C(18)H(20)Br(2)N(2)O(2), the heterocyclic ring adopts a chair conformation. The benzene rings make dihedral angles of 86.84 (10) and 60.73 (10)° with the mean plane of the heterocyclic ring. The dihedral angle between the two benzene rings is 79.77 (10)°. The mol-ecular structure is stabilized by two intra-molecular hydrogen bonds between the phenolic hy-droxy groups and N atoms with graph-set motif S(6). The crystal structure is stabilized by weak C-H⋯π inter-actions.
