Be2AuAg is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Be2AuAg cluster. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a single-bond geometry to one Ag(1) atom. The Be(1)-Ag(1) bond length is 1.07 Å. In the second Be site, Be(2) is bonded in a distorted single-bond geometry to one Ag(1) atom. The Be(2)-Ag(1) bond length is 0.79 Å. Au(1) is bonded in a single-bond geometry to one Ag(1) atom. The Au(1)-Ag(1) bond length is 0.79 Å. Ag(1) is bonded in a distorted trigonal non-coplanar geometry to one Be(1), one Be(2), and one Au(1) atom.
