Abstract: The first binuclear iron fullerene derivative of(η2-C60 )[Fe(CO)2(C5H5)]2 , which was yellow brown and sensitive to air and moisture, was prepared by the reaction of trans-[Fe(CO)2(C5H5)]2 with C60 in benzene under an atmosphere of dried nitrogen using conventional Schlenk techniques and has been characterized by using elementary analysis and IR, 1H NMR, 13C NMRand XPSspectra. The infrared spectrum of the title compound indicates the disappearance of νCO at 1760 cm-1 for bridge carbonyl and the appearance of the only terminal COlying at a higher wave number than that of the starting material, which reveals the electron-deficient behavior of C60 . And the important 1H, 13C NMRchemical shift and XPSof trans-[Fe(CO)2(C5H5)]2 , C60 and its novel complex along with their relative assignments are briefly discussed.
