摘要

An anion form of a lanthanum dirtier with C_(80) cage (La_2@C_(80)~-) was obtained by chemical and electrochemical reduction. The La_2@C_(80)~-anion exhibited the characteristic Electron Spin Resonance (ESR) pattern for the spin-doublet radical having very large hyper fine coupling (hfc) interaction with the identical two La nuclei. The exact values of hfc and g-tensor were determined by ESR measurements with two different frequencies, i.e. 9.5GHz (X-band) and 95GHz (W-band). Two La ions were identical, however, they formed a dimer and were fixed at the certain position within the C_(80)(I_h) cage. The total symmetry of La_2@C_(80)~- anion was D_(2h). The picture of the electronic state was changed from those of a neutral form of La_2@C_(80)by the injection of an excess electron. `
