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 .
Metal complex of buckminsterfullerene, (η2-C60)[Pt(PPh3)2]8,has been synthe-sized for the first time. It has been characterized by IR, XPS spectra as well as elementary analysis. The results show that the number bonded Pt(PPh3)2 to C60 is 8.
The fullerene complex,C60 RuH2(CO)(PPh3),has been prepared and characterize d by elemental analyses,IR and electronic spectra.In addition,the redox property of t he complex has been studied by cyclic voltammetry.The results s how that the reduction potential of C60 RuH2(CO)(PPh3)is more negative than that of C60.Meanwhile,with the extent of the complex reduction get to increace the stability of the complex ion is on the decrease.
