HfMnGe crystallizes in the hexagonal P-62m space group. Hf(1) is bonded in a 11-coordinate geometry to six equivalent Mn(1), one Ge(2), and four equivalent Ge(1) atoms. Mn(1) is bonded in a 4-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(2) is bonded in a 9-coordinate geometry to three equivalent Hf(1) and six equivalent Mn(1) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Hf(1) and three equivalent Mn(1) atoms.
HfMnGe crystallizes in the hexagonal P-62m space group. Hf(1) is bonded in a 11-coordinate geometry to six equivalent Mn(1), one Ge(2), and four equivalent Ge(1) atoms. There are two shorter (2.97 Å) and four longer (3.07 Å) Hf(1)-Mn(1) bond lengths. The Hf(1)-Ge(2) bond length is 2.78 Å. All Hf(1)-Ge(1) bond lengths are 2.77 Å. Mn(1) is bonded in a 4-coordinate geometry to six equivalent Hf(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. Both Mn(1)-Ge(1) bond lengths are 2.58 Å. Both Mn(1)-Ge(2) bond lengths are 2.52 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Hf(1) and six equivalent Mn(1) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Hf(1) and three equivalent Mn(1) atoms.
