The crystal structure described by Sc3RhC4 crystallizes in the monoclinic C2/m space group. There are three inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 12-coordinate geometry to four equivalent Rh(1), four equivalent C(1), and four equivalent C(2) atoms. In the second Sc site, Sc(2) is bonded in a 6-coordinate geometry to two equivalent C(1) and four equivalent C(2) atoms. In the third Sc site, Sc(3) is bonded in a 6-coordinate geometry to two equivalent C(2) and four equivalent C(1) atoms. Rh(1) is bonded in a distorted square co-planar geometry to four equivalent Sc(1), two equivalent C(1), and two equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded to one Sc(2), two equivalent Sc(1), two equivalent Sc(3), one Rh(1), and one C(1) atom to form a mixture of distorted corner, face, and edge-sharing CSc5RhC pentagonal bipyramids. In the second C site, C(2) is bonded to one Sc(3), two equivalent Sc(1), two equivalent Sc(2), one Rh(1), and one C(2) atom to form a mixture of distorted corner, face, and edge-sharing CSc5RhC pentagonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
