Abstract :
The first di-yttrium carbide endohedral metallofullerene has been produced and spectroscopically and structurally characterized. 13C NMR structural analyses reveal that di-yttrium endohedral metallofullerene having a molecular formula of Y2C84 has been found to possess an endohedral yttrium carbide structure, (Y2C2)@C82, in which a Y2C2 species is encaged by a C82-C3v(8) fullerene. The encaged Y2C2 species should rapidly rotate in order to maintain the entire (Y2C2)@C82 molecular symmetry unchanged at room temperature.
