CeRhIn5 crystallizes in the tetragonal P4/mmm space group. Ce(1) is bonded to four equivalent In(1) and eight equivalent In(2) atoms to form CeIn12 cuboctahedra that share corners with four equivalent Ce(1)In12 cuboctahedra, faces with four equivalent Ce(1)In12 cuboctahedra, and faces with four equivalent In(1)Ce4In8 cuboctahedra. Rh(1) is bonded in a body-centered cubic geometry to eight equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded to four equivalent Ce(1) and eight equivalent In(2) atoms to form distorted InCe4In8 cuboctahedra that share corners with four equivalent In(1)Ce4In8 cuboctahedra, faces with four equivalent Ce(1)In12 cuboctahedra, and faces with four equivalent In(1)Ce4In8 cuboctahedra. In the second In site, In(2) is bonded in a 4-coordinate geometry to two equivalent Ce(1), two equivalent Rh(1), and two equivalent In(1) atoms.
