BeSnSb is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BeSnSb cluster. Be(1) is bonded in a single-bond geometry to one Sn(1) atom. The Be(1)-Sn(1) bond length is 2.51 Å. Sn(1) is bonded in a distorted single-bond geometry to one Be(1) and one Sb(1) atom. The Sn(1)-Sb(1) bond length is 0.63 Å. Sb(1) is bonded in a single-bond geometry to one Sn(1) atom.
