The structure described by Sc2C3 is Plutonium carbide structured and crystallizes in the cubic I-43d space group. Sc(1) is bonded in a 6-coordinate geometry to six equivalent C(1) atoms. C(1) is bonded to four equivalent Sc(1) and one C(1) atom to form a mixture of distorted edge and corner-sharing CSc4C trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
