title: 2,4,6,8-Tetra-kis(4-chloro-phen-yl)-3,7-diaza-bicyclo-[3.3.1]nonan-9-one O-benzyl-oxime acetone monosolvate.
abstract: In the title compound, C(38)H(31)Cl(4)N(3)O·C(3)H(6)O, the 3,7-diaza-bicycle exists in a chair-boat conformation. The 4-chloro-phenyl groups attached to the chair form are equatorially oriented at an angle of 18.15 (3)° with respect to each other, whereas the 4-chloro-phenyl groups attached to the boat form are oriented at an angle of 32.64 (3)°. In the crystal, mol-ecules are linked by N-H⋯π and C-H⋯O inter-actions.
