Be2WZn crystallizes in the triclinic P1 space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a 4-coordinate geometry to one Be(2), two equivalent W(1), and one Zn(1) atom. The Be(1)-Be(2) bond length is 1.46 Å. There is one shorter (2.04 Å) and one longer (2.55 Å) Be(1)-W(1) bond length. The Be(1)-Zn(1) bond length is 2.44 Å. In the second Be site, Be(2) is bonded in a 3-coordinate geometry to one Be(1), one W(1), and one Zn(1) atom. The Be(2)-W(1) bond length is 2.44 Å. The Be(2)-Zn(1) bond length is 2.04 Å. W(1) is bonded in a 1-coordinate geometry to one Be(2), two equivalent Be(1), and one Zn(1) atom. The W(1)-Zn(1) bond length is 1.30 Å. Zn(1) is bonded in a distorted single-bond geometry to one Be(1), one Be(2), and one W(1) atom.
