N'-[(E)-5-Bromo-2-hy-droxy-3-meth-oxy-benzyl-idene]benzohydrazide monohydrate.
The title compound, C15H13BrN2O3·H2O, exists in an E conformation with respect to the azo-methane 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 intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, some hydrazide mol-ecules are replaced by mol-ecules of the 6-bromo isomer. The Br atom from this admixture was refined to give a partial occupancy of 0.0443 (19). A supra-molecular network is built in the lattice by means of inter-molecular N-H⋯O and two O-H⋯O inter-actions together with non-classical C-H⋯O inter-actions involving the lattice water mol-ecule stacking the mol-ecules along the b-axis direction.
