چکیده
In the title compound, C(31)H(24)F(4)N(2)O, the bicyclo-[3.3.1]nonane ring exists in a chair-boat conformation. Two of the four fluorine-substituted rings adopt equatorial dispositions with the piperidin-4-one rings. Mol-ecules are linked into a two-dimensional network parallel to (01) by N-H⋯O, C-H⋯F and C-H⋯O hydrogen bonds. Inter-molecular N-H⋯π and C-H⋯π inter-actions are also observed.
