Sr Zn Zn Ge
SrZn2Ge crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrZn2Ge cluster. Sr(1) is bonded in a 2-coordinate geometry to one Zn(1), one Zn(2), and one Ge(1) atom. The Sr(1)-Zn(1) bond length is 1.12 Å. The Sr(1)-Zn(2) bond length is 1.12 Å. The Sr(1)-Ge(1) bond length is 2.88 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 2-coordinate geometry to one Sr(1) and one Zn(2) atom. The Zn(1)-Zn(2) bond length is 0.99 Å. In the second Zn site, Zn(2) is bonded in a 1-coordinate geometry to one Sr(1), one Zn(1), and one Ge(1) atom. The Zn(2)-Ge(1) bond length is 2.59 Å. Ge(1) is bonded in a 2-coordinate geometry to one Sr(1) and one Zn(2) atom.
