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 the Schiff base molecules and the water molecules are linked together by intermolecular N—H⋯O and O—H⋯O hydrogen bonds, leading to layers parallel to the bc plane. An intramolecular O—H⋯N hydrogen bond involving the imine N atom and a hydroxy substituent is also observed.

An ethanolic solution (15 ml) of 3,5-dihydroxybenzohydrazide (0.67 g, 4 mmol) and 5-bromosalicylaldehyde (0.8 g, 4 mmol) was refluxed for 2 h. The solution was then cooled and the solid product formed was filtered off, washed with cold ethanol, and dried over silica gel. Crystals of the title compound were obtained by slow evaporation of a DMSO solution at room temperature.
The carbon-bound H atoms were placed in calculated positions (C—H fixed to 0.93 Å) and treated as riding on their parent carbon atoms with Uiso(H) set to 1.2 Ueq(carrier C). The nitrogen- and oxygen-bound H atoms were located in a difference map and refined as free atoms, with N—H and O—H distances restrained to 0.86 (2) and 0.82 (2) Å, respectively.
The molecular structure of the title compound is shown in Fig. 1, and the
in Fig. 2. The present study shows that Br and Cl analogues (Deng et al., 2009) are isotypic crystals.For the isotypic Cl analogue C14H11ClN2O4.H2O, see: Deng et al. (2009).
