BeGaSb2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BeGaSb2 clusters. Be(1) is bonded in a single-bond geometry to one Sb(2) atom. The Be(1)-Sb(2) bond length is 2.09 Å. Ga(1) is bonded in a single-bond geometry to one Sb(1) atom. The Ga(1)-Sb(1) bond length is 1.73 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a water-like geometry to one Ga(1) and one Sb(2) atom. The Sb(1)-Sb(2) bond length is 1.43 Å. In the second Sb site, Sb(2) is bonded in a water-like geometry to one Be(1) and one Sb(1) atom.
