Özet

In the title compound, C6H4BrF3N4O2, the oxadiazole ring is essentially planar with a maximum deviation of 0.003 (2) A . In the crystal, molecular pairs are connected by N-H N hydrogen bonds, forming dimers with an R22 (8) motif. The dimers are linked into layers parallel to the (104) plane by N-H O hydrogen bonds. In addition, C-O π and C-Br π interactions connect the molecules, forming a three-dimensional network. The F atoms of the trifluoromethyl group are disordered over two sites in a 0.515 (6): 0.485 (6) ratio. The intermolecular interactions in the crystal structure were investigated and quantified using Hirshfeld surface analysis.
