چکیده
The organic molecule of the title hydrate, C(15)H(13)BrN(2)O(4)·H(2)O, is roughly planar, with a mean deviation of 0.0939 (2) Å. The dihedral angle between the two aromatic rings is 8.2 (3)°. Intra-molecular O-H⋯N and O-H⋯O hydrogen bonds are observed. In the crystal, N-H⋯O(water) and O(water)-H⋯O hydrogen bonds lead to a three-dimensional network.
