X-ray diffraction and dielectric measurement have been applied to investigate the phase transition and transport properties of Sr0.56C60O1.5which is obtained by the reaction of SrCl2with C60anion aquatic solution. The new compound has a similar structure, but different transport properties as compared with metallic Sr-doped C60. X-ray diffraction shows that a first-order phase transition around 100°C is related to the rearrangement of Sr2+in the interstitial sites of the C60lattice. The step change of ac conductivity near 100°C is also attributed to the hopping of Sr2+between interstitial sites. The ionic conductivity indicates the possibility of synthesizing superionic conductors based on C60and its derivatives.
