The interaction of C 60 fullerene with the cis ‐dihydride osmium complex [OsH 2 (CO)(PPh 3 ) 3 ] ( I ) in the presence of t BuNC gives a novel metal complex [(η 2 ‐C 60 )Os(CO)‐( t BuNC)(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, 1 H 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 t BuNC as axial ligands.
