Be Sn Ge Ge
BeSn(Ge)2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ge2h6 molecule and one BeSn cluster. In the BeSn cluster, Be(1) is bonded in a single-bond geometry to one Sn(1) atom. The Be(1)-Sn(1) bond length is 0.43 Å. Sn(1) is bonded in a single-bond geometry to one Be(1) atom.
