The title compound, C 11 H 8 Br 2 N 4 , is a Schiff base obtained from 6-bromo­picolinaldehyde and 5-bromo­pyridine-3,4-diamine. The mol­ecule has an  E  configuration about the C=N bond and the dihedral angle between the two pyridine rings is 14.02 (1)°. The observed conformation is stabilised by an intramolecular N—H⋯N hydrogen bond. In the crystal, mol­ecules are stacked along the  b  axis and are linked through N—H⋯N hydrogen bonds into chains along the  c  axis.
