The novel physical and chemical properties of endeohedral metallofullernens are very important for their potential application in electronical and medical fields and attract extensive attention from researchers. In this paper, we describe the process of efficient preparation of endeohedral metallofullernen Y@C-82; we aslo investigate it by EXAFS at low temperatures (25K) and deal with the EXAFS data at different k range. The structure parameters of the first two shells are obtained and they are similar at different k range. However, there are large static disorders even at low temperature.
