Abstract
In the mol-ecular structure of the title Schiff base, C14H10Br2ClNO, the chloro-phenyl ring and di-bromo-phenol ring are almost coplanar; the dihedral angle between the planes of the two rings is 10.50 (18)°. There is an intra-molecular O-H⋯N hydrogen bond, with an O⋯N distance of 2.576 (4)Å. The crystal structure is stabilized by π-π stacking of neighbouring aromatic rings along the b-axis direction [centroid-centroid distance = 3.6896 (5) Å].Entities:

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