WAuBi2 is alpha Niobium phosphide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two WAuBi2 clusters. W(1) is bonded in a distorted single-bond geometry to one Bi(1) atom. The W(1)-Bi(1) bond length is 1.46 Å. Au(1) is bonded in a bent 120 degrees geometry to one Bi(1) and one Bi(2) atom. The Au(1)-Bi(1) bond length is 1.68 Å. The Au(1)-Bi(2) bond length is 1.68 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a water-like geometry to one W(1) and one Au(1) atom. In the second Bi site, Bi(2) is bonded in a distorted single-bond geometry to one Au(1) atom.
