YRhIn5 crystallizes in the tetragonal P4/mmm space group. Y(1) is bonded to four equivalent In(2) and eight equivalent In(1) atoms to form YIn12 cuboctahedra that share corners with four equivalent Y(1)In12 cuboctahedra, faces with four equivalent Y(1)In12 cuboctahedra, and faces with four equivalent In(2)Y4In8 cuboctahedra. Rh(1) is bonded in a body-centered cubic geometry to eight equivalent In(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 4-coordinate geometry to two equivalent Y(1), two equivalent Rh(1), and two equivalent In(2) atoms. In the second In site, In(2) is bonded to four equivalent Y(1) and eight equivalent In(1) atoms to form InY4In8 cuboctahedra that share corners with four equivalent In(2)Y4In8 cuboctahedra, faces with four equivalent Y(1)In12 cuboctahedra, and faces with four equivalent In(2)Y4In8 cuboctahedra.

All Y(1)-In(2) bond lengths are 3.28 Å. All Y(1)-In(1) bond lengths are 3.23 Å. Rh(1) is bonded in a body-centered cubic geometry to eight equivalent In(1) atoms. All Rh(1)-In(1) bond lengths are 2.75 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 4-coordinate geometry to two equivalent Y(1), two equivalent Rh(1), and two equivalent In(2) atoms. Both In(1)-In(2) bond lengths are 3.23 Å. In the second In site, In(2) is bonded to four equivalent Y(1) and eight equivalent In(1) atoms to form InY4In8 cuboctahedra that share corners with four equivalent In(2)Y4In8 cuboctahedra, faces with four equivalent Y(1)In12 cuboctahedra, and faces with four equivalent In(2)Y4In8 cuboctahedra.
