Abstract
The radii of the interstitial sites of (AsF6-)(1.9)C-60 in a tetragona l lattice are determined by geometrical means. The radii of the two oc tahedral sites constrained only by the six neighbouring C-60 molecules have maximum values of 2.66 Angstrom and 2.85 Angstrom. The two tetra hedral sites have optimum radii of 3.11 Angstrom and 2.65 Angstrom. An estimate of the size of the AsF6- ion shows that it can fit into the larger tetrahedral site. This indicates that (ASF(6)(-))(x)C-60 is an intercalation compound. (C) 1997 Elsevier Science Ltd.
