Abstract

The reaction of Ir₄(CO)₈(PMe₃)₄ with excess C₆₀ in refluxing 1,2-dichlorobenzene, followed by treatment by CNR (R = CH₂C₆H₅) at 70 °C, affords a fullerene?metal sandwich complex Ir₄(CO)₃(μ₄-CH)(PMe₃)₂(μ-PMe₂)(CNR)(μ-η²,η^2-C₆₀)(μ₄-η¹,η¹,η²,η²-C₆₀) (1), which exhibits an interesting structural feature of two metal atoms bridging the two C₆₀ centers as well as the first example of a μ₄-η¹,η¹,η²,η²-C₆₀ bonding mode. Compound 1 has been characterized by NMR spectroscopy, elemental analysis, and X-ray diffraction study. A cyclic voltammetry study reveals strong electronic communication between the two C₆₀ centers in 1, which is due to the presence of a wide channel of two metal centers between the two C₆₀ cages for efficient electronic interaction.
