CeRhGe3 crystallizes in the tetragonal I4mm space group. Ce(1) is bonded in a 17-coordinate geometry to five equivalent Rh(1), four equivalent Ge(2), and eight equivalent Ge(1) atoms. Rh(1) is bonded in a 5-coordinate geometry to five equivalent Ce(1), one Ge(2), and four equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 2-coordinate geometry to four equivalent Ce(1), two equivalent Rh(1), and two equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to four equivalent Ce(1), one Rh(1), and four equivalent Ge(1) atoms.
CeRhGe3 crystallizes in the tetragonal I4mm space group. Ce(1) is bonded in a 17-coordinate geometry to five equivalent Rh(1), four equivalent Ge(2), and eight equivalent Ge(1) atoms. There is one shorter (3.41 Å) and four longer (3.51 Å) Ce(1)-Rh(1) bond lengths. All Ce(1)-Ge(2) bond lengths are 3.21 Å. There are four shorter (3.24 Å) and four longer (3.45 Å) Ce(1)-Ge(1) bond lengths. Rh(1) is bonded in a 5-coordinate geometry to five equivalent Ce(1), one Ge(2), and four equivalent Ge(1) atoms. The Rh(1)-Ge(2) bond length is 2.39 Å. All Rh(1)-Ge(1) bond lengths are 2.43 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 2-coordinate geometry to four equivalent Ce(1), two equivalent Rh(1), and two equivalent Ge(2) atoms. Both Ge(1)-Ge(2) bond lengths are 2.72 Å. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to four equivalent Ce(1), one Rh(1), and four equivalent Ge(1) atoms.
