Materials Data on YZnGe by Materials Project
YZnGe crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 12-coordinate geometry to six equivalent Zn and six equivalent Ge atoms. All Y–Zn bond lengths are 2.94 Å. All Y–Ge bond lengths are 3.26 Å. In the second Y site, Y is bonded to six equivalent Ge atoms to form distorted edge-sharing YGe6 octahedra. All Y–Ge bond lengths are 3.04 Å. Zn is bonded in a 3-coordinate geometry to three equivalent Y and three equivalent Ge atoms. All Zn–Ge bond lengths are 2.51 Å. Ge is bonded in a 6-coordinate geometry to six Y and three equivalent Zn atoms.
