ResumoWe report the preparation of Cs3C60 by direct reaction of Cs vapor on C60. As against K3C60 and Rb3C60 which are both face centered cubic (fcc), Cs3C60 is body-centered cubic (bcc). Cs1C60 was also prepared and found to be fcc, but we did not observe any phase separation, as reported by Tycko et al. for KxC60 (0 <x < 3). This is the first evidence that the octahedral sites of the C60 lattice can be preferentially filled by alkali metal atoms.
