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.
