The material described by Sc3RhC4 crystallizes in the orthorhombic Immm space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded to four equivalent Rh(1) and eight equivalent C(1) atoms to form distorted ScRh4C8 cuboctahedra that share corners with four equivalent Sc(1)Rh4C8 cuboctahedra, corners with eight equivalent C(1)Sc5RhC pentagonal bipyramids, edges with two equivalent Sc(1)Rh4C8 cuboctahedra, edges with eight equivalent C(1)Sc5RhC pentagonal bipyramids, and faces with two equivalent Sc(1)Rh4C8 cuboctahedra. In the second Sc site, Sc(2) is bonded in a 6-coordinate geometry to six equivalent C(1) atoms. Rh(1) is bonded in a distorted square co-planar geometry to four equivalent Sc(1) and four equivalent C(1) atoms. C(1) is bonded to two equivalent Sc(1), three equivalent Sc(2), one Rh(1), and one C(1) atom to form distorted CSc5RhC pentagonal bipyramids that share corners with two equivalent Sc(1)Rh4C8 cuboctahedra, corners with thirteen equivalent C(1)Sc5RhC pentagonal bipyramids, edges with two equivalent Sc(1)Rh4C8 cuboctahedra, edges with five equivalent C(1)Sc5RhC pentagonal bipyramids, and faces with three equivalent C(1)Sc5RhC pentagonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
