Be2CoSb is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Be2CoSb cluster. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a linear geometry to one Co(1) and one Sb(1) atom. The Be(1)-Co(1) bond length is 0.39 Å. The Be(1)-Sb(1) bond length is 0.82 Å. In the second Be site, Be(2) is bonded in a single-bond geometry to one Co(1) atom. The Be(2)-Co(1) bond length is 0.39 Å. Co(1) is bonded in a linear geometry to one Be(1) and one Be(2) atom. Sb(1) is bonded in a single-bond geometry to one Be(1) atom.
