Deskripsi
In the title compound, C16H15BrN2O5·2H2O, the dihedral angle between the two aromatic rings is 2.9 (2)° and an intramolecular O—H...N hydrogen bond is observed. One of the water molecule is disordered over two positions, with occupancies of 0.83 (3) and 0.17 (3). In the crystal structure, molecules are linked into a three-dimensional network by intermolecular O—H...O, O—H...(O,O), O—H...N and N—H...O hydrogen bonds. π–π interactions involving Br-substituted benzene rings, with a centroid–centroid distance of 3.552 (3) Å are also observed.
