Tl Tl Hg Pt
PtHgTl2 is alpha Po structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one PtHgTl2 cluster. Pt(1) is bonded in a distorted L-shaped geometry to one Tl(1) and one Tl(2) atom. The Pt(1)-Tl(1) bond length is 1.93 Å. The Pt(1)-Tl(2) bond length is 1.45 Å. Hg(1) is bonded in a distorted L-shaped geometry to one Tl(1) and one Tl(2) atom. The Hg(1)-Tl(1) bond length is 1.45 Å. The Hg(1)-Tl(2) bond length is 1.93 Å. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a distorted L-shaped geometry to one Pt(1) and one Hg(1) atom. In the second Tl site, Tl(2) is bonded in a 2-coordinate geometry to one Pt(1) and one Hg(1) atom.
