Tl Sn Sn Ge
TlSnGeSn is alpha oxygen-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one lambda2-germanylidenetin molecule and one TlSn cluster. In the TlSn cluster, Tl(1) is bonded in a single-bond geometry to one Sn(2) atom. The Tl(1)-Sn(2) bond length is 1.12 Å. Sn(2) is bonded in a single-bond geometry to one Tl(1) atom.
