چکیده
The crystal of the title compound, C(21)H(23)NO(2), was chosen from a conglomerate formed by a racemic mixture. An intra-molecular hydrogen bond is formed between hy-droxy group and heterocyclic N atom of the aza-bicyclo-[3.2.1]octan-3-one system. The crystal structure is stabilized by C-H⋯O inter-actions between aliphatic C-H groups and the carbonyl O atom. For the title chiral crystal, the highly redundant and accurate diffraction data set collected with low energy copper radiation gave a Flack parameter of 0.12 (18) for anomalous scattering effects originating from O atoms.

In the title compound, C(13)H(13)FN(2)O(3), the fused piperidine ring is in a chair conformation. The fused pyrrolidine ring shows an envelope conformation with the N atom displaced by 0.661 (3) Å out of the plane formed by the four C atoms of the pyrrolidine ring. The dihedral angle between this plane and the plane formed by the four attached C atoms of the piperidine ring (not including the c...
