WPt2Al crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two WPt2Al clusters. W(1) is bonded in a single-bond geometry to one Pt(1) atom. The W(1)-Pt(1) bond length is 0.87 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one W(1) and one Al(1) atom. The Pt(1)-Al(1) bond length is 2.69 Å. In the second Pt site, Pt(2) is bonded in a distorted single-bond geometry to one Al(1) atom. The Pt(2)-Al(1) bond length is 2.47 Å. Al(1) is bonded in a distorted linear geometry to one Pt(1) and one Pt(2) atom.
