摘要：

There are two independent molecules in the asymmetric unit of the title compound, C13H9BrClN3O2, in which the dihedral angles between the benzene and pyridine rings are 8.23 (9)degrees and 52.84 (12)degrees. Both the molecules exist in an E configuration with respect to the C=N double bond. The two molecules in the asymmetric unit are linked via weak C-H center dot center dot center dot O hydrogen bonds. In both the molecules, an intramolecular O-H center dot center dot center dot N hydrogen bond generate an S(6) graph-set motif. In the crystal, intermolecular N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds generate bifurcated R-2(1)(7) ring motifs. The crystal packing is further stabilized by weak intermolecular N-H center dot center dot center dot O, N-H center dot center dot center dot N, C-H center dot center dot center dot O and pi-pi [centroid-centroid distance 3.615 (2) angstrom] interactions.
