Materials Data on GdZnGe by Materials Project

GdZnGe crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Gd sites. In the first Gd site, Gd is bonded in a 12-coordinate geometry to six equivalent Zn and six equivalent Ge atoms. All Gd–Zn bond lengths are 2.96 Å. All Gd–Ge bond lengths are 3.29 Å. In the second Gd site, Gd is bonded to six equivalent Ge atoms to form distorted edge-sharing GdGe6 octahedra. All Gd–Ge bond lengths are 3.06 Å. Zn is bonded in a 6-coordinate geometry to three equivalent Gd and three equivalent Ge atoms. All Zn–Ge bond lengths are 2.53 Å. Ge is bonded in a 6-coordinate geometry to six Gd and three equivalent Zn atoms.

Materials Data on Gd2(Zn2Ge)3 by Materials Project

Gd2(Zn2Ge)3 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Gd is bonded in a 6-coordinate geometry to nine Zn and six equivalent Ge atoms. There are three shorter (3.23 Å) and six longer (3.41 Å) Gd–Zn bond lengths. All Gd–Ge bond lengths are 3.12 Å. There are two inequivalent Zn sites. In the first Zn site, Zn is bonded in a 3-coordinate geometry to four equivalent Gd and three equivalent Ge atoms. There are one shorter (2.50 Å) and two longer (2.65 Å) Zn–Ge bond lengths. In the second Zn site, Zn is bonded in a distorted water-like geometry to two equivalent Gd and two equivalent Ge atoms. Both Zn–Ge bond lengths are 2.52 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Gd and five Zn atoms.
