WPt2Pb crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one WPt2Pb cluster. W(1) is bonded in a distorted single-bond geometry to one Pb(1) atom. The W(1)-Pb(1) bond length is 1.73 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one Pt(2) atom. The Pt(1)-Pt(2) bond length is 0.78 Å. In the second Pt site, Pt(2) is bonded in a 2-coordinate geometry to one Pt(1) and one Pb(1) atom. The Pt(2)-Pb(1) bond length is 1.97 Å. Pb(1) is bonded in a distorted linear geometry to one W(1) and one Pt(2) atom.
