Zn Pt Pt Br
Pt2ZnBr crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Pt2ZnBr cluster. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 2-coordinate geometry to one Pt(2) and one Zn(1) atom. The Pt(1)-Pt(2) bond length is 0.93 Å. The Pt(1)-Zn(1) bond length is 0.83 Å. In the second Pt site, Pt(2) is bonded in a 3-coordinate geometry to one Pt(1), one Zn(1), and one Br(1) atom. The Pt(2)-Zn(1) bond length is 0.87 Å. The Pt(2)-Br(1) bond length is 2.10 Å. Zn(1) is bonded in a 2-coordinate geometry to one Pt(1) and one Pt(2) atom. Br(1) is bonded in a single-bond geometry to one Pt(2) atom.
