The crystal structure described by CeLaRh4 is Cubic Laves-derived structured and crystallizes in the trigonal R3m space group. Ce(1) is bonded in a 12-coordinate geometry to three equivalent Rh(2) and nine equivalent Rh(1) atoms. La(1) is bonded in a 12-coordinate geometry to three equivalent Rh(2) and nine equivalent Rh(1) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded to three equivalent Ce(1), three equivalent La(1), and six equivalent Rh(1) atoms to form a mixture of corner, edge, and face-sharing RhLa3Ce3Rh6 cuboctahedra. In the second Rh site, Rh(1) is bonded to three equivalent Ce(1), three equivalent La(1), two equivalent Rh(2), and four equivalent Rh(1) atoms to form a mixture of corner, edge, and face-sharing RhLa3Ce3Rh6 cuboctahedra. is represented by the CIF card [CIF]
