Optically active rhodium and iridium C60 complexes containing the enantiomeric ligand (+)DIOP: (η2-C60)MH(CO)[(+)DIOP] (M=Rh, Ir)

The fullerene–metal complexes (η²-C₆₀)MH(CO)[(+)DIOP] (M=Ir, Rh) have been prepared by the exchange reaction of PPh₃ in corresponding (η²-C₆₀)MH(CO)(PPh₃)₂ for the chelate optically active ligand (+)DIOP [(+)-2,3-O-isopropylidene-2,3-dihydroxy-1,4-bis(diphenylphosphino)ethane] and their structures assigned.
