BeOsSb is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BeOsSb clusters. Be(1) is bonded in a single-bond geometry to one Sb(1) atom. The Be(1)-Sb(1) bond length is 0.25 Å. Os(1) is bonded in a distorted single-bond geometry to one Sb(1) atom. The Os(1)-Sb(1) bond length is 0.07 Å. Sb(1) is bonded in a linear geometry to one Be(1) and one Os(1) atom.
