Fe Bi Ir Ir
FeIr2Bi is Copper structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one FeIr2Bi cluster. Fe(1) is bonded in a 2-coordinate geometry to one Ir(1) and one Bi(1) atom. The Fe(1)-Ir(1) bond length is 0.54 Å. The Fe(1)-Bi(1) bond length is 0.54 Å. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a single-bond geometry to one Fe(1), one Ir(2), and one Bi(1) atom. The Ir(1)-Ir(2) bond length is 0.32 Å. The Ir(1)-Bi(1) bond length is 0.22 Å. In the second Ir site, Ir(2) is bonded in a 2-coordinate geometry to one Ir(1) and one Bi(1) atom. The Ir(2)-Bi(1) bond length is 0.32 Å. Bi(1) is bonded in a single-bond geometry to one Fe(1), one Ir(1), and one Ir(2) atom.
