摘要

The interaction of C_(60) fullerene with the cis-dihydride osmium complex [OsH_2(CO)(PPh_3)_3](I) in the presence of tBuNC gives a novel metal complex [η~2-C_(60)Os(CO)(tBuNC)(PPh_3)_2](II) as the first mononuclear osmium complex with an η~2-coordinated fullerene ligand. Complex II was isolated and characterized by elemental analysis, UV, IR, ~1H and ~(31)P NMR spectroscopy. An X-ray diffraction study of II as its dichlorobenzene solvate revealed a distorted trigonal bipyramidal coordination of the Os atom, with a 6/6 bond of C_(60) and two PPh_3 ligands in the equatorial plane and CO and tBuNC as axial ligands.
