2,4-Bis(4-fluoro-phen-yl)-3-aza-bicyclo-[3.3.1]nonan-9-one
Abstract:
In the title compound, C(20)H(19)F(2)NO, a crystallographic mirror plane bis-ects the mol-ecule, passing through the N, O and two C atoms of the central ring system. The mol-ecule exists in a twin-chair conformation with equatorial dispositions of the 4-fluoro-phenyl groups on both sides of the secondary amino groups; the dihedral angle between the aromatic ring planes is 28.67 (3)°.
