Abstract
The title compound, C(14)H(11)BrN(2)O(2), was synthesized by the reaction of 4-hydroxy-benzaldehyde with an equimolar quantity of 3-bromo-benzohydrazide in methanol. The dihedral angle between the two benzene rings is 40.1 (2)°. In the crystal structure, mol-ecules are linked through inter-molecular O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds to form a three-dimensional network.Entities:

| 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. |
