WSnGe2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one WSnGe2 cluster. W(1) is bonded in a distorted single-bond geometry to one Sn(1), one Ge(1), and one Ge(2) atom. The W(1)-Sn(1) bond length is 1.29 Å. The W(1)-Ge(1) bond length is 0.70 Å. The W(1)-Ge(2) bond length is 0.70 Å. Sn(1) is bonded in a 2-coordinate geometry to one W(1) and one Ge(2) atom. The Sn(1)-Ge(2) bond length is 1.11 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 2-coordinate geometry to one W(1) and one Ge(2) atom. The Ge(1)-Ge(2) bond length is 0.72 Å. In the second Ge site, Ge(2) is bonded in a distorted single-bond geometry to one W(1), one Sn(1), and one Ge(1) atom.
