INTERCALATION OF ASF5 IN C-60

The product of a solid solution reaction of C-60 and AsF5 in liquid SO 2 is reported. The change of weight of the C-60 by the reaction indica tes that there is (AsF5)(x)C-60 with x = 1.88 +/- 0.04. Mass spectrosc opy identifies the AsF5 and C-60. The x-ray diffraction is distinctly different from that of C-60 and can be indexed with a body-centered-te tragonal unit cell. The infrared spectrum has an absorption at 702 cm( -1) which is not present in C-60.
