Bi Bi Bi Bi Ir Ir
IrBi2 is Cubic alpha N2-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two IrBi2 clusters. Ir(1) is bonded in a distorted single-bond geometry to one Bi(2) atom. The Ir(1)-Bi(2) bond length is 0.45 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a single-bond geometry to one Bi(2) atom. The Bi(1)-Bi(2) bond length is 1.17 Å. In the second Bi site, Bi(2) is bonded in a distorted single-bond geometry to one Ir(1) and one Bi(1) atom.
