PtTlBi2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one PtTlBi2 cluster. Pt(1) is bonded in a 3-coordinate geometry to one Tl(1), one Bi(1), and one Bi(2) atom. The Pt(1)-Tl(1) bond length is 1.80 Å. The Pt(1)-Bi(1) bond length is 0.91 Å. The Pt(1)-Bi(2) bond length is 1.80 Å. Tl(1) is bonded in a 1-coordinate geometry to one Pt(1) and one Bi(2) atom. The Tl(1)-Bi(2) bond length is 2.04 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a single-bond geometry to one Pt(1) atom. In the second Bi site, Bi(2) is bonded in a 2-coordinate geometry to one Pt(1) and one Tl(1) atom.
