Sn Sn Ge W
WSn2Ge crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one WSn2Ge cluster. W(1) is bonded in a linear geometry to one Sn(1) and one Sn(2) atom. The W(1)-Sn(1) bond length is 1.82 Å. The W(1)-Sn(2) bond length is 1.82 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a bent 120 degrees geometry to one W(1) and one Ge(1) atom. The Sn(1)-Ge(1) bond length is 0.81 Å. In the second Sn site, Sn(2) is bonded in a single-bond geometry to one W(1) atom. Ge(1) is bonded in a single-bond geometry to one Sn(1) atom.
