Abstract

Mössbauer measurements were carried out over the range 8060 (ferrocene)2. Ferrocene was also measured at room temperature. The obtained Mössbauer parameters showed that there is no measurable chemical interaction between C60 and ferrocene but the slightly decreased isomer shift of decamethyl-ferrocene (compared to that of ferrocene) demonstrated that the donor character of the methyl groups can have an effect on the electronic structure of iron (through the cp rings), as well. The asymmetry of the Mössbauer lines was explained by both the Goldanskii - Karyagin effect and texture of the samples. The texture was found to be dominant in decamethyl-ferrocene and the Goldanskii-Karyagin effect results in the major part of asymmetry in fullerene(ferrocene)2.
