Zr Zr Hg Pt
Zr2PtHg crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Zr2PtHg cluster. There are two inequivalent Zr sites. In the first Zr site, Zr(1) is bonded in a distorted single-bond geometry to one Pt(1) and one Hg(1) atom. The Zr(1)-Pt(1) bond length is 2.13 Å. The Zr(1)-Hg(1) bond length is 0.63 Å. In the second Zr site, Zr(2) is bonded in a single-bond geometry to one Hg(1) atom. The Zr(2)-Hg(1) bond length is 0.92 Å. Pt(1) is bonded in a 1-coordinate geometry to one Zr(1) atom. Hg(1) is bonded in a bent 120 degrees geometry to one Zr(1) and one Zr(2) atom.
