Abstract

The title complex, (triphos)RhH(η²-C₆₀) (2) (triphos=CH₃C(CH₂PPh₂)₃), was prepared by the reaction (80°C, toluene) of C₆₀ with a trihydride rhodium complex (triphos)RhH₃ (1) in high yield (86%) as green crystals and characterized by spectroscopic (mass, ¹H-, ³¹P-, and ¹³C-NMR) and analytical data. The molecular structure of 2 was determined by a single crystal X-ray diffraction study. The rhodium atom is octahedrally coordinated by three fac-phosphorus atoms, a hydrogen atom and an η²-C₆₀ ligand. The cyclic voltammetric study of 2 reveals two reversible redox waves which are shifted to more negative potentials by ca. 290 mV compared to free C₆₀, reflecting both metal-to-C₆₀ π-back-donation effect and the electron-donating nature of the triphos ligand.
