We report the structural and magnetic properties of the endohedral metallofullerene Ce@C82. A hexagonal close packing phase [P63/mmc [a=lI.1544Å, c=18.2256Å] is formed exclusively after vacuum annealing of the solvent precipitated compound. In contrast, sublimed Ce@C82 was found to be dominantly face-centred cubic close packed [Fm-3m; a=15.766Å]. X-ray powder profile calculations revealed that the endohedral cerium atom lies close to 1.8Å from the C82 cage centre in both phases. Hexagonal Ce@C82 has been investigated by magnetic susceptibility measurements. Paramagnetic behaviour is maintained down to 2K attributable to Ce3+ ions. Towards lower temperatures, the observed paramagnetic moment falls from the free ion Ce3+(neff =2.54μ8) value, monotonically approaching IpB at 2K.
