5-[(E)-2-Bromobenzylidene]-8-(2-bromophenyl)-2-hydroxy-10-methyl-3,10-diazahexacyclo[10.7.1.13,7.02,11.07,11.016,20]henicosa-1(20),12,14,16,18-pentaen-6-one

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) 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].
