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.展开更多
The fullerene compound CoC 60(OH) has been prepared by the reaction of C - 60 anion with Co(Ⅱ) hydrous salt under nitrogen atmosphere and refluxing, and the title compound is characterized by FAB-MS, elemental analys...The fullerene compound CoC 60(OH) has been prepared by the reaction of C - 60 anion with Co(Ⅱ) hydrous salt under nitrogen atmosphere and refluxing, and the title compound is characterized by FAB-MS, elemental analysis, FT-IR, XPS, UV-Vis and 1H NMR. The results prove the presence of C-Co and -OH groups in the resultant, and coovalent of Co bonding to C 60. The apparent charge distribution of the resultant appeaers to be Co 2+C - 60(OH) -, and there are three kinds of carbons with different electron density. The result of redox experiment indicates that the reduction potential of the compound is more negative than that of pure C 60.展开更多
