Be Be Ga Sb
Be2GaSb is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Be2GaSb clusters. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a distorted single-bond geometry to one Sb(1) atom. The Be(1)-Sb(1) bond length is 1.95 Å. In the second Be site, Be(2) is bonded in a distorted single-bond geometry to one Ga(1) atom. The Be(2)-Ga(1) bond length is 1.73 Å. Ga(1) is bonded in a single-bond geometry to one Be(2) and one Sb(1) atom. The Ga(1)-Sb(1) bond length is 0.46 Å. Sb(1) is bonded in a single-bond geometry to one Be(1) and one Ga(1) atom.
