Bi Bi Ir Ru
RuIrBi2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RuIrBi2 clusters. Ru(1) is bonded in a distorted L-shaped geometry to two equivalent Bi(1) atoms. Both Ru(1)-Bi(1) bond lengths are 1.75 Å. Ir(1) is bonded in a distorted L-shaped geometry to two equivalent Bi(1) atoms. Both Ir(1)-Bi(1) bond lengths are 1.75 Å. Bi(1) is bonded in a distorted L-shaped geometry to one Ru(1) and one Ir(1) atom.
