Abstract

The mol-ecule of the title compound, C19H13Br2N3O2, lies about a twofold rotation axis. The benzene ring makes dihedral angles of 8.9 (2) and 16.4 (2)° with the central pyridine ring and the second benzene ring, respectively. An intra-molecular N-H⋯N contact occurs. In the crystal, mol-ecules are connected by pairs of N-H⋯O hydrogen bonds into chains along the c axis.
