title: 2,4,6,8-Tetra-kis(4-bromo-phen-yl)-3,7-diaza-bicyclo-[3.3.1]nonan-9-one.
abstract: In the title compound, C(31)H(24)Br(4)N(2)O, one of the bromo-phenyl rings is disordered over two orientations with occupancies of 0.69 (2) and 0.31 (2). The bicyclo-[3.3.1]nonane ring system adopts a chair-boat conformation. In the crystal structure, mol-ecules are linked into chains along the c axis by inter-molecular C-H⋯O and N-H⋯O hydrogen bonds. Further stabilization is provided by C-H⋯π inter-actions.
