Abstract: The title compound, C20H21IO, was synthesized by cyclo­haloetherification of 2-(cyclo­hex-2-en­yl)-2,2-diphenyl­ethanol in CH2Cl2, and crystallized with two independent mol­ecules in the asymmetric unit. The six-membered cyclo­hexane ring adopts a chair conformation, while the five-membered ring adopts an envelope conformation with the fused C atom opposite the O atom as the flap in each case [displacements of the flap atoms = 0.6813 (3) and 0.6679 (3) Å]. In the crystal, mol­ecules are linked via pairs of C-H...[pi] inter­actions, forming inversion dimers.
