Si Bi Bi Au
AuSiBi2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AuSiBi2 clusters. Au(1) is bonded in a distorted single-bond geometry to one Si(1), one Bi(1), and one Bi(2) atom. The Au(1)-Si(1) bond length is 1.50 Å. The Au(1)-Bi(1) bond length is 3.00 Å. The Au(1)-Bi(2) bond length is 2.29 Å. Si(1) is bonded in a distorted single-bond geometry to one Au(1) and one Bi(2) atom. The Si(1)-Bi(2) bond length is 2.26 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a distorted single-bond geometry to one Au(1) atom. In the second Bi site, Bi(2) is bonded in a 2-coordinate geometry to one Au(1) and one Si(1) atom.
