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 1.40 (15)°. There are two short intra-molecular inter-actions (N-H⋯Br and C-H⋯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 3.6484 (19) to 3.7942 (19) Å.
