title: 16-[(E)-4-Bromo-benzyl-idene]-13-(4-bromo-phen-yl)-2-hy-droxy-11-methyl-1,11-diaza-penta-cyclo-[12.3.1.0.0.0]octa-deca-3(8),4,6-triene-9,15-dione.
abstract: In the title pyrrolidine compound, C(30)H(24)Br(2)N(2)O(3), the two fused pyrrolidine rings adopt envelope and twisted conformations, whereas the piperidine ring adopts an envelope conformation. The essentially planar 2,3-dihydro-indanone unit [maximum deviation = -0.0163 (19) Å] is inclined at inter-planar angles of 14.29 (9) and 61.07 (9)° to the two benzene rings. In the crystal, adjacent mol-ecules are linked into dimers by inter-molecular O-H⋯N and C-H⋯O hydrogen bonds. Short inter-molecular Br⋯Br inter-actions [3.5140 (6) Å] further inter-connect these dimers into double dimeric columns along the b axis.
