Zn Si Si Au
AuZnSi2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one AuZnSi2 cluster. Au(1) is bonded in a single-bond geometry to one Zn(1) atom. The Au(1)-Zn(1) bond length is 0.19 Å. Zn(1) is bonded in a distorted single-bond geometry to one Au(1) and one Si(2) atom. The Zn(1)-Si(2) bond length is 0.95 Å. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a single-bond geometry to one Si(2) atom. The Si(1)-Si(2) bond length is 0.91 Å. In the second Si site, Si(2) is bonded in a distorted linear geometry to one Zn(1) and one Si(1) atom.
