[(μ-H)3Re3(CO)9(η2,η2,η2-Sc2C2@C(3v)(8)-C(82))]: face-capping cluster complex of an endohedral fullerene.

Like a miniature trophy, the complex pictured was obtained as the sole product from the reaction of Sc(2)C(2)@C(3v)(8)-C(82) and [(μ-H)(3)Re(3)(CO)(11)(NCMe)] and characterized by IR, visible/near-infrared, and NMR spectroscopy, mass spectrometry, and X-ray diffraction. Coordination of the Re(3) cluster to the unique hexagon oriented perpendicular to the C(3) axis of the fullerene core altered the geometry and electronic properties of Sc(2)C(2)@C(3v)(8)-C(82).
