Fullerene and its derivant have unique poperties on physics and chemistry. The main purposes of the synthesis of new type of fullerene complexes is to exploit the applications of fullerene and its derivant as functional materials. In the present work, the fullerene complexe C60Ni(PPh3)2 was perpared by the method of ligand substitution via the reaction of C60with NiCl2(PPh3)2 under the condition of a nitrogen atmosphere and refluxing, and the title compound was appraised and characterized by methods of elemental analysis , FTIR, UVvis, XPS.The results showed that the structure of purposeful product was that the PPh3 took up two coordination sites of the central metal, and C60 took up another two sites in σπ feeback pattern.The result of redox research indicated that the reduction potential of the complexe was more negative than that of the pure C60.
