Abstract
In the title compound, C33H26Br2N2O2, 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) angstrom. The dihedral angle between the two bromophenyl rings is 60.19 (8)degrees. An intramolecular O-H center dot center dot center dot N interaction is observed, generating an S(5) ring motif. The crystal structure is stabilized by intermolecular C-H center dot center dot center dot O interactions. Short Br center dot center dot center dot Br [3.461 (1) angstrom] and Br center dot center dot center dot C [3.322 (2) angstrom] intermolecular contacts are observed, as well as pi-pi interactions [centroid-centroid distance = 3.793 (1) angstrom].
