Sumario: | The asymmetric unit of the title compound, C(15)H(12)Br(2)F(3)NO(2), consists of two crystallographically independent molecules. In both molecules, the pyrrolidine and tetrahydrofuran rings adopt an envelope conformation. In the crystal, molecule pairs generate centrosymmetric rings with R (2) (2)(8) motifs linked by C—H⋯O hydrogen bonds. These pairs of molecules form a tetrameric supramolecular motif, leading to molecular layers parallel to the (100) plane by C—H⋯π and C—Br⋯π interactions. Interlayer van der Waals and interhalogen interactions stabilize molecular packing. The F atoms of the CF(3) groups of both molecules are disordered over two sets of sites with refined site occupancies of 0.60 (3)/0.40 (3) and 0.640 (15)/0.360 (15). The most important contributions to the surface contacts of both molecules are from H⋯H (23.8 and 22.4%), Br⋯H/H⋯Br (18.3 and 12.3%), O⋯H/H⋯O (14.3 and 9.7%) and F⋯H/H⋯F (10.4 and 19.1%) interactions, as concluded from a Hirshfeld surface analysis. |
