Аннотация:Lithium fullerides LinC60 prepared by liquid-phase intercalation, solid-state reaction, and a mixed process were studied by IR spectroscopy. The fullerides obtained by liquid-phase intercalation can be divided, according to their structure, into three groups: solid solutions (n = 1-4), polymerized phases containing lithium clusters between fullerene chains (n = 4-12), and partially depolymerized phases with two inequivalent types of lithium atoms (n = 12-30). The spect a of the fullerides with a = 2-3 prepared by solid-stare reaction are similar to those of the polymerized fullerides with n much greater than 4 prepared by liquid-phase intercalation. The structure of the fullerides produced by the mixed process varies from that of photopolymerized C-60 films (n similar or equal to 1) to orthorhombic (n similar or equal to 4).
