YWSn2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YWSn2 clusters. Y(1) is bonded in a 3-coordinate geometry to one W(1) and two equivalent Sn(1) atoms. The Y(1)-W(1) bond length is 1.63 Å. Both Y(1)-Sn(1) bond lengths are 1.38 Å. W(1) is bonded in a 3-coordinate geometry to one Y(1) and two equivalent Sn(1) atoms. Both W(1)-Sn(1) bond lengths are 1.38 Å. Sn(1) is bonded in a 2-coordinate geometry to one Y(1) and one W(1) atom.
