Abstract
The title mol-ecule, C(14)H(11)BrN(2)O(2), displays a trans configuration about the C=N and C-N bonds. The dihedral angle between the two benzene rings is 18.5 (3)°. An intra-molecular O-H⋯N hydrogen bond is observed. In the crystal structure, the mol-ecules are linked into a chain along the c axis by N-H⋯O and C-H⋯O hydrogen bonds.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. |
