Abstract
In the title molecule, C18H19BrN2O, the benzene ring is inclined to the oxadiazole ring by 10.44 (8)degrees. In the crystal, C-H center dot center dot center dot pi interactions link the molecules in a head-to-tail fashion, forming chains extending along the c-axis direction. The chains are further connected by pi-pi stacking interactions, with centroid-centroid distances of 3.6385 (7) angstrom, forming layers parallel to the bc plane.
