Abstract

In the title compound, C33H26Br2N2O 2, the piperidine group adopts an envelope conformation while the two pyrrolidine groups adopt half-chair and envelope conformations. The dihydroacenaphthylene group is almost planar, with a maximum deviation of 0.105 (1) Å. The dihedral angle between the two bromophenyl rings is 60.19 (8)°. An intramolecular O-H⋯N interaction is observed, generating an S(5) ring motif. The crystal structure is stabilized by intermolecular C-H⋯O interactions. Short Br⋯Br [3.461 (1) Å] and Br⋯C [3.322 (2) Å] intermolecular contacts are observed, as well as π-π interactions [centroid-centroid distance = 3.793 (1) Å].
