Undistorted structures of compounds with C₆H₆ and C₆F₆ groups linked by (CH₂)₃ and (CH₂)₂SiMe₂ moieties show folding by intramolecular dispersion forces in the gas phase whereas in the solid state, extended conformers are adopted that interact intermolecularly. The experimental data served as a reference for the quality of quantum-chemical calculations.
