Abstract
IT has been shown recently that MxC60 (M = alkali metal) is metallic at 300 K for some M and x (ref. 1) and superconducts below 18 K for M = potassium2. These observations give further impetus to studies of the molecular3 and solid-state4 properties of fullerenes. Here we report on X-ray diffraction studies of the structure and bonding in alkali-metal-doped solid C60 (fullerite). Powder diffraction data obtained from equilibrium compositions of C60 doped to saturation with K or Cs show that the face-centred cubic lattice of pure C60 (refs 5–7) transforms to body-centred cubic at these doping levels, with a saturation composition close to M6C60. The rotational disorder of the fullerene molecules in pure C60 at 300 K is absent in the fully doped compounds.
