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\sb 20H\sb 16F\sb 2O\sb 3. The dihedral angles between the two fluoro\-phenyl rings are 79.7(2) and 73.7(2)\circ 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⋅sO inter\-actions help to stabilize the crystal structure.
