Abstract:
The asymmetric unit of the title compound, C11H9Br2N3O, contains two crystallographically independent mol-ecules with similar geometries; the Br-C-C=O torsion angles are 1.2 (4) and -2.8 (4)°, and the benzene and triazole rings are inclined o one another by 51.90 (16) and 51.88 (16)°. The two molecules are related by a pseudo-screw 21 axis directed along [100]. In the crystal, mol-ecules are linked into a three-dimensional network by weak C-H⋯O and C-H⋯N hydrogen bonds and secondary Br⋯Br [3.5991 (8) and 3.6503 (9) Å] inter-actions.
