HfRhGe crystallizes in the hexagonal P-62m space group. Hf(1) is bonded in a 11-coordinate geometry to six equivalent Rh(1), one Ge(2), and four equivalent Ge(1) atoms. Rh(1) is bonded in a 12-coordinate geometry to six equivalent Hf(1), two equivalent Rh(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Hf(1) and three equivalent Rh(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Hf(1) and six equivalent Rh(1) atoms.
HfRhGe crystallizes in the hexagonal P-62m space group. Hf(1) is bonded in a 11-coordinate geometry to six equivalent Rh(1), one Ge(2), and four equivalent Ge(1) atoms. There are two shorter (2.90 Å) and four longer (3.13 Å) Hf(1)-Rh(1) bond lengths. The Hf(1)-Ge(2) bond length is 2.80 Å. All Hf(1)-Ge(1) bond lengths are 2.77 Å. Rh(1) is bonded in a 12-coordinate geometry to six equivalent Hf(1), two equivalent Rh(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. Both Rh(1)-Rh(1) bond lengths are 2.83 Å. Both Rh(1)-Ge(1) bond lengths are 2.52 Å. Both Rh(1)-Ge(2) bond lengths are 2.55 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Hf(1) and three equivalent Rh(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Hf(1) and six equivalent Rh(1) atoms.
