چکیده
In the title mol-ecule, C18H19BrN2O, the benzene ring is inclined to the oxa-diazole ring by 10.44 (8)°. In the crystal, C-H⋯π inter-actions link the mol-ecules in a head-to-tail fashion, forming chains extending along the c-axis direction. The chains are further connected by π-π stacking inter-actions, with centroid-centroid distances of 3.6385 (7) Å, forming layers parallel to the bc plane.
