The fullerene complex, η 2 C 60 [Ru(NO)(PPh 3)] 2, has been prepared by the reaction of C 60 with Ru(NO) 2(PPh 3) 2 under a nitrogen atmosphere and refluxing. The new complex was characterized by means of elemental analysis, IR, XPS, electronic spectra and 31 P NMR. The results show that the complex of η 2 form can be formed by C 60 bonding to Ru(NO) 2(PPh 3) 2 in the σ π way and there is hyperconjugation effect in the molecule. So electrons will flow easier and photoelectric effect for this new compound is expected. In addition, the structure of the complex has been supposed. The ruthenium is 4 coordinate in the complex, bonding to two carbon atoms, to one PPh 3 and to one NO.
The hydroxyl fullerene salt AgmC60(OH)n(NO3)m was prepared by reaction of fullerenols and silver nitrate,and characterized by elemental analysis,IR and XPS.In addition,the thermostability of the compound has been studied by thermoanalysis.The result show that the number of n is about 18-19,which is the same as that in C60(OH)n,the number of m is 9-10,and the temperature of AgmC60(OH)n(NO3)m decompounding to carbon dioxide is lower than that of C60(OH)
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 .
