HoZnGe crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 12-coordinate geometry to six equivalent Zn(1) and six equivalent Ge(1) atoms. In the second Ho site, Ho(2) is bonded to six equivalent Ge(1) atoms to form distorted edge-sharing HoGe6 octahedra. Zn(1) is bonded in a 6-coordinate geometry to three equivalent Ho(1) and three equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to three equivalent Ho(1), three equivalent Ho(2), and three equivalent Zn(1) atoms.
HoZnGe crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 12-coordinate geometry to six equivalent Zn(1) and six equivalent Ge(1) atoms. All Ho(1)-Zn(1) bond lengths are 2.90 Å. All Ho(1)-Ge(1) bond lengths are 3.22 Å. In the second Ho site, Ho(2) is bonded to six equivalent Ge(1) atoms to form distorted edge-sharing HoGe6 octahedra. All Ho(2)-Ge(1) bond lengths are 3.00 Å. Zn(1) is bonded in a 6-coordinate geometry to three equivalent Ho(1) and three equivalent Ge(1) atoms. All Zn(1)-Ge(1) bond lengths are 2.47 Å. Ge(1) is bonded in a 9-coordinate geometry to three equivalent Ho(1), three equivalent Ho(2), and three equivalent Zn(1) atoms.
