The remarkably large cluster Sc4(μ3-O)2 has been obtained trapped inside an Ih-C80 cage by conducting the vaporization of graphite rods doped with copper(II) nitrate and scandium(III) oxide in an electric arc under a low pressure helium atmosphere with an added flow of air. The product has been isolated by chromatography and identified by high-resolution mass spectrometry. The structure of Sc4(μ3-O)2@Ih-C80 has been determined by X-ray crystallography on a crystal of Sc4(μ3-O)2@Ih-C80·NiII(OEP)·2(C6H6). The Sc4(μ3-O)2 unit consists of a distorted tetrahedron of scandium atoms with oxygen atoms bridging two of its faces. The Sc−Sc distances range from 2.946(7) to 3.379(7) Å.
