WPtAs2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two WPtAs2 clusters. W(1) is bonded in a 1-coordinate geometry to one Pt(1) and two equivalent As(1) atoms. The W(1)-Pt(1) bond length is 1.20 Å. Both W(1)-As(1) bond lengths are 1.44 Å. Pt(1) is bonded in a distorted single-bond geometry to one W(1) and two equivalent As(1) atoms. Both Pt(1)-As(1) bond lengths are 1.44 Å. As(1) is bonded in a 3-coordinate geometry to one W(1), one Pt(1), and one As(1) atom. The As(1)-As(1) bond length is 1.20 Å.
