Abstract: The title compound, C15H13BrN2O3·H2O, exists in an E conformation with respect to the azo­methane C=N double bond. The benzene and phenyl rings form dihedral angles of 0.46 (2) and 4.90 (3)°, respectively with the central C(=O)N2C unit. An intra­molecular O-H...N hydrogen bond occurs. In the crystal, some hydrazide mol­ecules are replaced by mol­ecules of the 6-bromo isomer. The Br atom from this admixture was refined to give a partial occupancy of 0.0443 (19). A supra­molecular network is built in the lattice by means of inter­molecular N-H...O and two O-H...O inter­actions together with non-classical C-H...O inter­actions involving the lattice water mol­ecule stacking the mol­ecules along the b-axis direction.
