Be Be Ga Co
Be2CoGa is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Be2CoGa clusters. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a single-bond geometry to one Be(2) atom. The Be(1)-Be(2) bond length is 0.17 Å. In the second Be site, Be(2) is bonded in a single-bond geometry to one Be(1) and one Co(1) atom. The Be(2)-Co(1) bond length is 1.69 Å. Co(1) is bonded in a 1-coordinate geometry to one Be(2) and one Ga(1) atom. The Co(1)-Ga(1) bond length is 2.17 Å. Ga(1) is bonded in a distorted single-bond geometry to one Co(1) atom.
