Investigation of Paramagnetic Centers in Fullerides A_2MC_(60) and AM_2C_(60) (A=K, Rb, Cs, M=Mg, Be, Al)

摘要

Heterofullerides with the composition Cs_2MC_(60), Rb_2MC_(60), K_2MC_(60) and KM_2C_(60) (M=Mg, Be, Al) were synthesized by means of chemical reactions in organic solvents (toluene, tetrahydrofurane) [1, 2]. The synthesis consisted of two stages. First the fullerides of alkali metals were obtained during direct reactions of alkali metal and fullerite solution. And at the last stage the exchange reactions of alkali fullerides with chlorides or hydrides of other metals yielded heterofullerides.
