Be Ga Ga Ag
BeAgGa2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BeAgGa2 clusters. Be(1) is bonded in a single-bond geometry to one Ga(1) atom. The Be(1)-Ga(1) bond length is 1.05 Å. Ag(1) is bonded in a linear geometry to one Ga(1) and one Ga(2) atom. The Ag(1)-Ga(1) bond length is 0.87 Å. The Ag(1)-Ga(2) bond length is 0.87 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a linear geometry to one Be(1) and one Ag(1) atom. In the second Ga site, Ga(2) is bonded in a single-bond geometry to one Ag(1) atom.
