Table 1 is a summary of 14 different fullerides with their lattice parameters at room temperature, Tc and REion, including Cs3C60 under pressure and the Na3C60 and Li3C60 compounds. It should
be noted that it has not been possible so far to produce Li3C60 in a stable form and Na3C60 might partly transform into Na2C60 and Na6C60 [20
