Abstract
METALLIC and superconducting donor-type intercalation compounds of C60 are now well established. These involve electron transfer from a sublattice of alkali-metal dopants to a sublattice of fullerene molecules. Three stoichiometric phases have been identified1–3, and a binary phase diagram describing composition regions of two-phase coexistence has been proposed2. Oxidative intercalation by electron acceptors, meanwhile, has not previously been reported. Ohno et al.4 recently presented photoemission data suggesting that solid C60 will take up only minor amounts of iodine, resulting in a non-metallic product which is not a stoichiometric compound4. Here we report that, by using different reaction conditions, we have prepared a highly crystalline C60: iodine compound of ideal stoichiometry C60I4, with an alternating guest–host layer structure closely resembling that of classic intercalation compounds. The 300-K resistivity exceeds 109 Ωcm and we observe no superconductivity down to 4 K, despite the fact that the inter-fullerene separation lies in the range of that in the superconducting M3 C60 phases (where M is K, Rb, Cs). C60I4 is apparently the first example of a fullerite intercalation compound in which there is no electron transfer between C60 and the intercalate.
