The interaction of C60 fullerene with the cis-dihydride osmium complex [OsH2(CO)(PPh3)3] (I) in the presence of tBuNC gives a novel metal complex [(η2-C60)Os(CO)- (tBuNC)(PPh3)2] (II) as the first mononuclear osmium complex with an η2-coordinated fullerene ligand. Complex II was isolated and characterized by elemental analysis, UV, IR, 1H and 31P 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 C60 and two PPh3 ligands in the equatorial plane and CO and tBuNC as axial ligands.
