C60FEC60 COMPLEXES IN FE INTERCALATED FULLERITE STUDIED BY X-RAY-ABSORPTION

The aim of Fe K edge XANES and EXAFS studies is to reveal the local st ructure around Fe ions in C60Fex intercalated fullerites. The measurem ents are performed in transmission mode at LN2 temperature for C60Fex powder samples and other materials: ferrocene Fe(C5H5)(2) Fe metal foi l and alpha-Fe2O3. The main result is that the XAFS spectra of the C60 Fe2 intercalate is almost identical to that of ferrocene and very diff erent from alpha-Fe and alpha-Fe2O3. The results support opinion that in the C60Fex intercalates the ferrocene-like bonds in complexes C60Fe C60 are formed. Additionally, the XAFS spectra showed that neither rem arkable amount of Fe metallic clusters nor oxidized iron particles are present in the C60Fex sample.
