La2(Zn2Ge)3 crystallizes in the hexagonal P-62m space group. La(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 La(1) and three equivalent Ge(1) atoms. In the second Zn site, Zn(2) is bonded in a 2-coordinate geometry to two equivalent La(1) and two equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent La(1), two equivalent Zn(2), and three equivalent Zn(1) atoms.
La2(Zn2Ge)3 crystallizes in the hexagonal P-62m space group. La(1) is bonded in a 15-coordinate geometry to three equivalent Zn(2), six equivalent Zn(1), and six equivalent Ge(1) atoms. All La(1)-Zn(2) bond lengths are 3.26 Å. All La(1)-Zn(1) bond lengths are 3.44 Å. All La(1)-Ge(1) bond lengths are 3.17 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 3-coordinate geometry to four equivalent La(1) and three equivalent Ge(1) atoms. There is one shorter (2.56 Å) and two longer (2.62 Å) Zn(1)-Ge(1) bond lengths. In the second Zn site, Zn(2) is bonded in a 2-coordinate geometry to two equivalent La(1) and two equivalent Ge(1) atoms. Both Zn(2)-Ge(1) bond lengths are 2.53 Å. Ge(1) is bonded in a 9-coordinate geometry to four equivalent La(1), two equivalent Zn(2), and three equivalent Zn(1) atoms.
