ABSTRACT
In the title compound, C12H9BrN4O, the dihedral angle between the aromatic rings is 12.16â
(12)°. An intra-molecular N-Hâ¯N hydrogen bond closes an S(5) ring. In the crystal, C-Hâ¯O hydrogen bonds link the mol-ecules into C(6) chains propagating in [010]. Very weak aromatic π-π stacking [centroid-centroid separations = 3.9189â
(15) and 3.9357â
(15)â
Å] is also observed.
