The Schiff base molecule in the title compound, C14H11BrN2O4·H2O, is almost planar with an r.m.s. deviation for the non-H atoms of 0.16 Å. In the crystal structure, the Schiff base molecules and the water molecules are linked together by intermolecular N-HO and O-HO hydrogen bonds, leading to layers parallel to the bc plane. An intramolecular O-HN hydrogen bond involving the imine N atom and a hydroxy substituent is also observed.
