Zn Zn Zn Zn Au Au
AuZn2 is Hg_xSn structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one AuZn2 cluster. Au(1) is bonded in a distorted L-shaped geometry to one Au(1) and one Zn(1) atom. The Au(1)-Au(1) bond length is 1.24 Å. The Au(1)-Zn(1) bond length is 2.04 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a distorted bent 120 degrees geometry to one Au(1) and one Zn(2) atom. The Zn(1)-Zn(2) bond length is 0.86 Å. In the second Zn site, Zn(2) is bonded in a distorted single-bond geometry to one Zn(1) atom.
