Abstract:
The asymmetric unit of the title compound, C26H23FO2S, contains two independent mol-ecules (A and B), in both of which the cyclo-hexyl ring adopts a chair conformation. The benzo-furan ring systems, the 4-fluoro-phenyl and phenyl rings are essentially planar, with r.m.s. deviations of 0.008 (1), 0.002 (1) and 0.003 (1) Å, respectively, for mol-ecule A, and 0.016 (1), 0.004 (1) and 0.002 (1) Å, respectively, for mol-ecule B. The dihedral angles between the benzo-furan ring system and the pendant 4-fluoro-phenyl and phenyl rings are 12.3 (7) and 85.42 (4)°, respectively, for mol-ecule A, and 39.67 (6) and 72.17 (4)°, respectively, for mol-ecule B. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π inter-actions, resulting in a three-dimensional network.

For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
