The first binuclear iron fullerene derivative of(η 2 C 60 )[Fe(CO) 2(C 5H 5)] 2 , which was yellow brown and sensitive to air and moisture, was prepared by the reaction of trans [Fe(CO) 2(C 5H 5)] 2 with C 60 in benzene under an atmosphere of dried nitrogen using conventional Schlenk techniques and has been characterized by using elementary analysis and IR, 1H NMR, 13 C NMR and XPS spectra. The infrared spectrum of the title compound indicates the disappearance of ν CO at 1 760 cm -1 for bridge carbonyl and the appearance of the only terminal CO lying at a higher wave number than that of the starting material, which reveals the electron deficient behavior of C 60 . And the important 1H, 13 C NMR chemical shift and XPS of trans [Fe(CO) 2(C 5H 5)] 2 , C 60 and its novel complex along with their relative assignments are briefly discussed.
