title: Methyl 4,6-bis-(4-fluoro-phen-yl)-2-oxo-cyclo-hex-3-ene-1-carboxyl-ate.
abstract: The 3-cyclo-hexene units adopt envelope conformations in each of the two independent mol-ecules that comprise the asymmetric unit of the title compound, C(20)H(16)F(2)O(3). The dihedral angles between the two fluoro-phenyl rings are 79.7 (2) and 73.7 (2)° in the two mol-ecules. In one of the mol-ecules, two C-H groups of the cyclo-hexene ring are disordered over two sets of sites in a 0.818 (13):0.182 (13) ratio, the major and minor components corresponding to the two enanti-omeric forms of the mol-ecule. Weak inter-molecular C-H⋯O inter-actions help to stabilize the crystal structure.
