The crystal structure of 1,1,4,4‐tetrafluorocyclohexane has been determined from X‐ray diffraction measurements at 95 K. Internal motion of the CF 2 ‐group can be discerned from analysis of the atomic vibration tensors. The pattern of bond lengths suggests that an anomeric‐effect type of interaction between antiperiplanar C,C‐ and C,F‐bonds (as well as between C,H‐ and C,F‐bonds) may be operative in this molecule.
