Pt2W crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Pt2W cluster. W(1) is bonded in a single-bond geometry to one Pt(2) atom. The W(1)-Pt(2) bond length is 0.87 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 1-coordinate geometry to one Pt(2) atom. The Pt(1)-Pt(2) bond length is 1.31 Å. In the second Pt site, Pt(2) is bonded in a distorted linear geometry to one W(1) and one Pt(1) atom.
