CeRhC2 crystallizes in the tetragonal P4_3 space group. Ce(1) is bonded in a 14-coordinate geometry to six equivalent Rh(1), four equivalent C(1), and four equivalent C(2) atoms. Rh(1) is bonded in a 4-coordinate geometry to six equivalent Ce(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 in a 7-coordinate geometry to four equivalent Ce(1), two equivalent Rh(1), and one C(2) atom. In the second C site, C(2) is bonded in a 7-coordinate geometry to four equivalent Ce(1), two equivalent Rh(1), and one C(1) atom.
