Sn Bi Bi Ir
IrBi2Sn is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two 7439-88-5 atoms and two Bi2Sn clusters. In each Bi2Sn cluster, Sn(1) is bonded in a linear geometry to one Bi(1) and one Bi(2) atom. The Sn(1)-Bi(1) bond length is 0.15 Å. The Sn(1)-Bi(2) bond length is 1.04 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a single-bond geometry to one Sn(1) atom. In the second Bi site, Bi(2) is bonded in a single-bond geometry to one Sn(1) atom.
