title: 2,4-Bis(4-bromo-phen-yl)-3-aza-bicyclo-[3.3.1]nonan-9-one.
abstract: The title compound, C(20)H(19)Br(2)NO, shows a chair-chair conformation for the aza-bicycle with an equatorial disposition of the 4-bromo-phenyl groups [dihedral angle between the aromatic rings = 16.48 (3)°]. In the crystal, a short Br⋯Br contact [3.520 (4) Å] occurs and the structure is further stabilized by N-H⋯O hydrogen bonds and C-H⋯O inter-actions.
