Zn Si Bi Bi
ZnSiBi2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ZnSiBi2 cluster. Zn(1) is bonded in a distorted water-like geometry to one Bi(1) and one Bi(2) atom. The Zn(1)-Bi(1) bond length is 1.35 Å. The Zn(1)-Bi(2) bond length is 1.09 Å. Si(1) is bonded in a single-bond geometry to one Bi(2) atom. The Si(1)-Bi(2) bond length is 2.33 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a single-bond geometry to one Zn(1) atom. In the second Bi site, Bi(2) is bonded in a distorted single-bond geometry to one Zn(1) and one Si(1) atom.
