Be2AgZn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Be2AgZn cluster. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a distorted bent 150 degrees geometry to one Be(2) and one Zn(1) atom. The Be(1)-Be(2) bond length is 0.78 Å. The Be(1)-Zn(1) bond length is 1.08 Å. In the second Be site, Be(2) is bonded in a distorted single-bond geometry to one Be(1) atom. Ag(1) is bonded in a single-bond geometry to one Zn(1) atom. The Ag(1)-Zn(1) bond length is 0.34 Å. Zn(1) is bonded in a distorted single-bond geometry to one Be(1) and one Ag(1) atom.
