Abstract
In the crystal, molecular pairs are connected by N—H⋯N hydrogen bonds, forming dimers with an (8) motif. The dimers are linked into layers parallel to the (10 ) 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.
In the title compound, C6H4BrF3N4O2, the oxadiazole ring is essentially planar with a maximum deviation of 0.003 (2) Å. 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 (10 ) 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.
期刊介绍：
Acta Crystallographica Section E: Crystallographic Communications is the IUCr''s open-access structural communications journal. It provides a fast, simple and easily accessible publication mechanism for crystal structure determinations of inorganic, metal-organic and organic compounds. The electronic submission, validation, refereeing and publication facilities of the journal ensure rapid and high-quality publication of fully validated structures. The primary article category is Research Communications; these are peer-reviewed articles describing one or more structure determinations with appropriate discussion of the science.
