ABSTRACT
In title compound, C(12)H(11)Br(2)NO(2), the coumarin ring system is almost planar, the two rings being inclined to one another by 1.40â
(15)°. There are two short intra-molecular inter-actions (N-Hâ¯Br and C-Hâ¯Br) involving the Br atoms. In the crystal, mol-ecules stack along the a-axis direction via π-π inter-actions; the centroid-centroid distances vary from 3.6484â
(19) to 3.7942â
(19)â
Å.
