Gd3Zn5Ge crystallizes in the hexagonal P-62m space group. Gd(1) is bonded in a 11-coordinate geometry to four equivalent Zn(2), six equivalent Zn(1), and one Ge(1) atom. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 12-coordinate geometry to six equivalent Gd(1), two equivalent Zn(1), two equivalent Zn(2), and two equivalent Ge(1) atoms. In the second Zn site, Zn(2) is bonded in a 9-coordinate geometry to six equivalent Gd(1) and three equivalent Zn(1) atoms. Ge(1) is bonded in a distorted q6 geometry to three equivalent Gd(1) and six equivalent Zn(1) atoms.
Gd3Zn5Ge crystallizes in the hexagonal P-62m space group. Gd(1) is bonded in a 11-coordinate geometry to four equivalent Zn(2), six equivalent Zn(1), and one Ge(1) atom. All Gd(1)-Zn(2) bond lengths are 3.01 Å. There are two shorter (3.19 Å) and four longer (3.37 Å) Gd(1)-Zn(1) bond lengths. The Gd(1)-Ge(1) bond length is 3.00 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 12-coordinate geometry to six equivalent Gd(1), two equivalent Zn(1), two equivalent Zn(2), and two equivalent Ge(1) atoms. Both Zn(1)-Zn(1) bond lengths are 3.02 Å. Both Zn(1)-Zn(2) bond lengths are 2.73 Å. Both Zn(1)-Ge(1) bond lengths are 2.76 Å. In the second Zn site, Zn(2) is bonded in a 9-coordinate geometry to six equivalent Gd(1) and three equivalent Zn(1) atoms. Ge(1) is bonded in a distorted q6 geometry to three equivalent Gd(1) and six equivalent Zn(1) atoms.
