Abstract
The transmission and Raman spectra of C60H42 samples synthesized at a high hydrogen pressure and stored under different conditions have been measured. It has been found that, upon interaction of the compound with air, a part of C60-H chemical bonds are replaced by C60-O-H bonds. It has been experimentally shown that the observed changes in the vibrational and electronic properties of C60H42 are caused by the interaction of the compound with atmospheric oxygen and water vapor. The rate of oxidation of the studied samples is significantly less than the value previously published for the oxidation of the C60H36 compound synthesized by the reduction of fullerene C60 dissolved in different solvents with the use of Zn/HCl. This is explained by the fact that particles of the product of the hydrogenation at a high hydrogen pressure are polycrystals with relatively large sizes, unlike the fullerene hydrides synthesized by the reduction of C60 with Zn/HCl.
