Abstract:	Endohedral metallofullerenes Y₂@C₈₄, Ce₂@C₇₈, and M@C₈₂ (M = Y, Ce) were synthesized by the electric arc method and isolated from the soot using extraction with o-dichlorobenzene. Pure (98%) endohedral dimetallofullerenes Y₂@C₈₄ and Ce₂@C₇₈ were isolated for the first time from o-dichlorobenzene extracts using HPLC and characterized by mass spectrometry and spectrophotometry. Published in Russian in Izvestiya Akademii Nauk. Seriya Khimicheskaya, No. 11, pp. 2067–2071, November, 2007.

Keywords:	endohedral metallofullerenes electric arc synthesis extraction high-performance liquid chromatography mass spectrometry spectrophotometry
