5-Bromo-N-[(E)-(6-bromo-pyridin-2-yl)methyl-idene]pyridine-3,4-diamine.
The title compound, C(11)H(8)Br(2)N(4), is a Schiff base obtained from 6-bromo-picolinaldehyde and 5-bromo-pyridine-3,4-diamine. The mol-ecule 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, mol-ecules are stacked along the b axis and are linked through N-H⋯N hydrogen bonds into chains along the c axis.
