Abstract

We have investigated the rotor-stator molecular crystal fullerene-cubane (C60·C8H8) by 1H NMR spectroscopy in the temperature range of 130 to 380 K. The 1H line is broad and exhibits fine structure characteristic of a multispin spectrum, indicating the absence of angular reorientations of the cubane molecule. The temperature and field dependence of the spin-lattice relaxation rate of cubane protons is well explained in terms of field fluctuations arising from reorientations of the C60 molecules. Despite the closely packed structure, the activation energy of these reorientations, 650 K, is close to that observed in the high-temperature phase of pure C60 indicating that the static cubane molecules act as efficient bearing for the rotating fullerene molecules.
