Gd2(Zn2Ge)3 crystallizes in the hexagonal P-62m space group. Gd(1) is bonded in a 15-coordinate geometry to three equivalent Zn(2), six equivalent Zn(1), and six equivalent Ge(1) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 3-coordinate geometry to four equivalent Gd(1) and three equivalent Ge(1) atoms. In the second Zn site, Zn(2) is bonded in a distorted water-like geometry to two equivalent Gd(1) and two equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Gd(1), two equivalent Zn(2), and three equivalent Zn(1) atoms.
Gd2(Zn2Ge)3 crystallizes in the hexagonal P-62m space group. Gd(1) is bonded in a 15-coordinate geometry to three equivalent Zn(2), six equivalent Zn(1), and six equivalent Ge(1) atoms. All Gd(1)-Zn(2) bond lengths are 3.20 Å. All Gd(1)-Zn(1) bond lengths are 3.37 Å. All Gd(1)-Ge(1) bond lengths are 3.08 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 3-coordinate geometry to four equivalent Gd(1) and three equivalent Ge(1) atoms. There is one shorter (2.48 Å) and two longer (2.62 Å) Zn(1)-Ge(1) bond lengths. In the second Zn site, Zn(2) is bonded in a distorted water-like geometry to two equivalent Gd(1) and two equivalent Ge(1) atoms. Both Zn(2)-Ge(1) bond lengths are 2.49 Å. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Gd(1), two equivalent Zn(2), and three equivalent Zn(1) atoms.
