Materials Data on HoZnGe by Materials Project
HoZnGe crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 12-coordinate geometry to six equivalent Zn and six equivalent Ge atoms. All Ho–Zn bond lengths are 2.92 Å. All Ho–Ge bond lengths are 3.25 Å. In the second Ho site, Ho is bonded to six equivalent Ge atoms to form distorted edge-sharing HoGe6 octahedra. All Ho–Ge bond lengths are 2.99 Å. Zn is bonded in a 3-coordinate geometry to three equivalent Ho and three equivalent Ge atoms. All Zn–Ge bond lengths are 2.50 Å. Ge is bonded in a 6-coordinate geometry to six Ho and three equivalent Zn atoms.
