The fullerene complexes, η2-C70[RhCl（CO）（PPh3）2]n（n=1, 2）, have been prepared by the reaction of C70 with RhCl（CO）（PPh3）2 in methylbenzene at room temperature. The new complexes were characterized by UV-Vis spectra, IR, XPS and elemental analysis. The results show that the complexes of η2 form can be formed by RhCl（CO）（PPh3）2 bonding to C70 in theσ-π way. In addition, the complexes structures have been supposed.
The fullerene complexe C 60 Co (Pph 3 ) 2 has been prepared by the reaction of C 60 with CoCl 2 (Pph 3 ) 2 under a nitrogen atmosphere and refluxing,and characterized by elemental analyses,FT-IR,XPS,NMR,which appove that C 60 coordinates to Co (Pph 3 ) 2 group inσ-πpattern and the electron is super con jugate over whole molecule.The result of redox property study sh ow that the reduction potentiel of C 60 Co (Pph 3 ) 2 is more negative than that of C 60 ,the reason may be theπelectron dentensity of C 60 in C 60 Co (Pph 3 ) 2 increases,which lead to it’s electr on affinity decreasing.The thermosta bility experiment indicates that th e oxidation decomposition temperature of C 60 Co (Pph 3 ) 2 is lower than that of pure C 60 .
