Glycine C60 Adduct and its Rare Earth Complexes

ABSTRACT Glycine sodium salt reacts with C60 to give a water soluble derivative 1, acidification of which produces a less soluble product 2. When compound 2 is treated with Ln(CIO4)3 (Ln=La, Y) in several different molar ratios, insoluble rare earth complexes: C60 (Gly)xLnx/3(OH)y(H2O)z (x=7-8, y=4-6, z=2-6) were obtained. These new compounds have been characterized by IR.TG-DTA and XPS spectra.
