HfFeGe crystallizes in the hexagonal P-62m space group. Hf(1) is bonded in a 11-coordinate geometry to six equivalent Fe(1), one Ge(1), and four equivalent Ge(2) atoms. Fe(1) is bonded in a 10-coordinate geometry to six equivalent Hf(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 three equivalent Hf(1) and six equivalent Fe(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to six equivalent Hf(1) and three equivalent Fe(1) atoms.
HfFeGe crystallizes in the hexagonal P-62m space group. Hf(1) is bonded in a 11-coordinate geometry to six equivalent Fe(1), one Ge(1), and four equivalent Ge(2) atoms. There are two shorter (2.91 Å) and four longer (3.01 Å) Hf(1)-Fe(1) bond lengths. The Hf(1)-Ge(1) bond length is 2.74 Å. All Hf(1)-Ge(2) bond lengths are 2.72 Å. Fe(1) is bonded in a 10-coordinate geometry to six equivalent Hf(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. Both Fe(1)-Ge(1) bond lengths are 2.48 Å. Both Fe(1)-Ge(2) bond lengths are 2.54 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Hf(1) and six equivalent Fe(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to six equivalent Hf(1) and three equivalent Fe(1) atoms.
