N'-[(E)-1-(5-Bromo-2-hydroxy-phen-yl)ethyl-idene]benzohydrazide.

The C=N double bond in the title compound, C(15)H(13)BrN(2)O(2), is transE configured and the dihedral angle between the aromatic ring planes is 22.3 (1)°. The crystal structure is stabilized by intra-molecular O-H⋯O and inter-molecular N-H⋯O hydrogen bonds.

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 takeninto account individually in the estimation of e.s.d.'s in distances, anglesand torsion angles; correlations between e.s.d.'s in cell parameters are onlyused 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.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
