(1RS,6SR)-Ethyl 4,6-bis-(4-fluoro-phen-yl)-2-oxocyclo-hex-3-ene-1-carboxyl-ate.

In the crystal structure of the title compound, C(21)H(18)F(2)O(3), the cyclo-hexene ring has a slightly distorted sofa conformation; the two benzene rings are inclined by 76.27 (8)° and their planes make dihedral angles of 16.65 (10) and 67.53 (7)° with the approximately planar part of the cyclo-hexenone ring [maximum deviation 0.044 (2) Å, while the sixth atom is displaced by 0.648 (3) Å from this plane]. In the crystal, weak inter-molecular C-H⋯O, C-H⋯F and C-H⋯π inter-actions join mol-ecules into a three-dimensional structure.
