Abstract: In the title pyrrolidine compound, C₃₀H₂₄Br₂N₂O₃, the two fused pyrrolidine rings adopt envelope and twisted conformations, whereas the piperidine ring adopts an envelope conformation. The essentially planar 2,3-dihydroindanone unit [maximum deviation = -0.0163 (19) Å] is inclined at interplanar angles of 14.29 (9) and 61.07 (9)° to the two benzene rings. In the crystal, adjacent molecules are linked into dimers by intermolecular O-HN and C-HO hydrogen bonds. Short intermolecular BrBr interactions [3.5140 (6) Å] further interconnect these dimers into double dimeric columns along the b axis.
