The X-ray structure of Sc₃C₈₂ is redetermined by the MEM/Rietveld method by using synchrotron radiationpowder data at SPring-8, where the C₂ encapsulated structure available to discuss the Sc-Sc interatomicdistances has been determined. The encapsulated three scandium atoms form a triangle shape. A sphericalcharge distribution originating from the C₂ molecule is located at the center of the triangle. Interatomic distancesbetween Sc and Sc are 3.61(3) Å in the triangle. The distance between Sc and the center of the C₂ moleculeis 2.07(1) Å.
