(1RS, 6SR)-Ethyl 4,6-bis(4-fluorophenyl)-2-oxocyclohex-3-ene-1-carboxylate

In the crystal structure of the title compound, C21H18F2O3, the cyclohexene ring has a slightly distorted sofa conformation; the two benzene rings are inclined by 76.27 (8)degrees and their planes make dihedral angles of 16.65 (10) and 67.53 (7)degrees with the approximately planar part of the cyclohexenone ring [ maximum deviation 0.044 (2) angstrom, while the sixth atom is displaced by 0.648 (3) angstrom from this plane]. In the crystal, weak intermolecular C-H center dot center dot center dot O, C-H center dot center dot center dot F and C-H center dot center dot center dot pi interactions join molecules into a three-dimensional structure.
