The aim of Fe K edge XANES and EXAFS studies is to reveal the local structure around Fe ions in C_{60}Fe_{x} intercalated fullerites. The measurements are performed in transmission mode at LN_{2} temperature for C_{60}Fe_{x} powder samples and other materials: ferrocene Fe(C_{5}H_{5})_{2}, Fe metal foil and α-Fe_{2}O_{3}. The main result is that the XAFS spectra of the C_{60}Fe_{2} intercalate is almost identical to that of ferrocene and very different from α-Fe and α-Fe_{2}O_{3}. The results support opinion that in the C_{60}Fe_{x} intercalates the ferrocene-like bonds in complexes C_{60}FeC_{60} are formed. Additionally, the XAFS spectra showed that neither remarkable amount of Fe metallic clusters nor oxidized iron particles are present in the C_{60}Fe_{x} sample.
