Europium fullerides EuxC60 (x = 1-6) were prepared by metal ammonia solution synthesis. The products were investigated by X-ray powder diffraction, optical spectroscopy, FTIR, mass spectrometry, and magnetic susceptibility. All products were amorphous by powder X-ray diffraction and were free of ammonia as determined by mass spectrometry. Products prepared with x = 1, 2, 3 showed the presence of unreacted C60 in the optical spectra, FTIR spectra, and the powder diffraction pattern. FTIR spectra of the EuxC60 prepared with x = 3 show red-shifted frequencies of F1u(4) at 1399 and 1352 (1411) cm-1, suggesting the presence of C60 - and C60 6-. FTIR spectra of Eu1C6O samples prepared with x = 4, 5, 6 also show red-shifted frequencies and are discussed in detail. Magnetic susceptibility measurements show Curie-Weiss behavior above 50 K with experimental magnetic moments of 6.6 (1), 6.9 (1), and 5.9 (1) μB/Eu for x = 3, 4, 5 samples, respectively.
