ZnZrZr2Zn2Ge3 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ZnZr cluster and one Zr2Zn2Ge3 cluster. In the ZnZr cluster, Zr(1) is bonded in a distorted single-bond geometry to one Zn(2) atom. The Zr(1)-Zn(2) bond length is 0.72 Å. Zn(2) is bonded in a single-bond geometry to one Zr(1) atom. In the Zr2Zn2Ge3 cluster, there are two inequivalent Zr sites. In the first Zr site, Zr(2) is bonded in a 2-coordinate geometry to one Zn(3) and one Ge(2) atom. The Zr(2)-Zn(3) bond length is 1.36 Å. The Zr(2)-Ge(2) bond length is 1.46 Å. In the second Zr site, Zr(3) is bonded in a distorted bent 120 degrees geometry to one Ge(1) and one Ge(3) atom. The Zr(3)-Ge(1) bond length is 1.73 Å. The Zr(3)-Ge(3) bond length is 1.22 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 2-coordinate geometry to one Zn(3) and one Ge(1) atom. The Zn(1)-Zn(3) bond length is 0.61 Å. The Zn(1)-Ge(1) bond length is 0.77 Å. In the second Zn site, Zn(3) is bonded in a distorted single-bond geometry to one Zr(2), one Zn(1), and one Ge(1) atom. The Zn(3)-Ge(1) bond length is 0.70 Å. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 2-coordinate geometry to one Zr(3), one Zn(1), and one Zn(3) atom. In the second Ge site, Ge(2) is bonded in a 1-coordinate geometry to one Zr(2) atom. In the third Ge site, Ge(3) is bonded in a distorted single-bond geometry to one Zr(3) atom.
