In the approximately planar title molecule, C14H10BrClN3O2, the dihedral angle between the aromatic ring planes is 5.79 (12)°. The conformation is stabilized by intramolecular O—H⋯N and N—H⋯O hydrogen bonds and an intermolecular O—H⋯O link leads to chains in the crystal propagating in [001].

2-Hydroxybenzohydrazide(0.60 g, 4 mmol) and 3-bromo-5-chloro-2-ydroxybenzaldehyde (0.94 g, 4 mmol) were heated in ethanol (30 ml) for 2 h. The solvent was removed by evaporation and the resulting solid was recrystallized from ethanol to yield yellow plates of (I).
The carbon-bound H-atoms were placed in calculated positions (C–H = 0.95 Å) and refined as riding with U(H) = 1.2U(C). The oxygen- and nitrogen-bound H-atoms were located in a difference map, and were refined with distance restraints of O–H 0.84±0.01 and N–H 0.88±0.01 Å. Their Uiso values were freely refined.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |

In the approximately planar title molecule, (I), (Fig. 1) the dihedral angle between the aromatic ring planes is 5.79 (12)°. The conformation is stabilised by intramolecular O—H···N and N—H···O hydrogen bonds and an intermolecular O—H···O link leads to chains in the crystal (Table 1).
