Synthesis and Characterization for(η2-C60 )[Fe(CO)2(C5H5)]2

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 ν_CO 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.
