Al Tl Ir Ir
Ir2TlAl is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ir2TlAl cluster. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a single-bond geometry to one Tl(1) and one Al(1) atom. The Ir(1)-Tl(1) bond length is 0.26 Å. The Ir(1)-Al(1) bond length is 1.01 Å. In the second Ir site, Ir(2) is bonded in a distorted single-bond geometry to one Tl(1) atom. The Ir(2)-Tl(1) bond length is 0.67 Å. Tl(1) is bonded in a single-bond geometry to one Ir(1), one Ir(2), and one Al(1) atom. The Tl(1)-Al(1) bond length is 1.01 Å. Al(1) is bonded in a 2-coordinate geometry to one Ir(1) and one Tl(1) atom.
