| Popis: | The asymmetric unit of the title compound, C30H27F2N3O2, contains two independent molecules. The pyrrolidine five-membered ring assumes an envelope conformation (with the CH2 atom at the flap) in one molecule and a twisted conformation in the other one. In both independent molecules, the 4-piperidinone rings adopt a similar twisted chair conformation. In the crystal, the two independent molecules form an R22(8) dimer through a pair of N—H...O hydrogen bonds; the R22(8) dimers are connected via weak C—H...O hydrogen bonds, leading to a chain extending along the c axis. |
