Abstract
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)° and 52.84 (12)°. 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⋯O hydrogen bonds. In both the molecules, an intramolecular O—H⋯N hydrogen bond generate an S(6) graph-set motif. In the crystal, intermolecular N—H⋯O and C—H⋯O hydrogen bonds generate bifurcated R 1 2(7) ring motifs. The crystal packing is further stabilized by weak intermolecular N—H⋯O, N—H⋯N, C—H⋯O and π–π [centroid–centroid distance 3.615 (2) Å] interactions.
