C60H18, C60H36 AND C70H36 FULLERENE HYDRIDES - STUDY BY METHODS OF IR, NMR, XPS, EELS AND MAGNETOCHEMISTRY

Fullerene hydrides of C60H18, C60H36 and C70H36 are studied by using I R, H-1 and C-13 NMR, X-ray photoelectron and electron energy loss spec troscopies, and magnetochemistry. The comparison of IR and solid state H-1 and C-13 NMR data for C60H36 With the theoretical ones allows the suggestion that fullerene hydride has a T symmetric structure and con tains 4 isolated benzenoid rings located at tetrahedral positions on t he surface of a closed skeleton of the molecule. The EELS revealed tha t the transition from fullerene to the hydride is accompanied by the d ecrease of the density of valence electrons. Magnetization measurement s showed C60H36 to be a ferromagnet. The hydrogenated fullerenes were prepared by transfer hydrogenation procedures involving 9,10-dihydroan thracene. The compositions of the hydrides are determined by field des orption mass-spectral analysis.
