Be2W is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded to six equivalent Be(2) and six equivalent W(1) atoms to form a mixture of face, corner, and edge-sharing BeBe6W6 cuboctahedra. In the second Be site, Be(2) is bonded to two equivalent Be(1), four equivalent Be(2), and six equivalent W(1) atoms to form a mixture of face, corner, and edge-sharing BeBe6W6 cuboctahedra. W(1) is bonded in a 12-coordinate geometry to three equivalent Be(1) and nine equivalent Be(2) atoms.

In the first Be site, Be(1) is bonded to six equivalent Be(2) and six equivalent W(1) atoms to form a mixture of face, corner, and edge-sharing BeBe6W6 cuboctahedra. All Be(1)-Be(2) bond lengths are 2.25 Å. All Be(1)-W(1) bond lengths are 2.61 Å. In the second Be site, Be(2) is bonded to two equivalent Be(1), four equivalent Be(2), and six equivalent W(1) atoms to form a mixture of face, corner, and edge-sharing BeBe6W6 cuboctahedra. There are two shorter (2.18 Å) and two longer (2.27 Å) Be(2)-Be(2) bond lengths. All Be(2)-W(1) bond lengths are 2.61 Å. W(1) is bonded in a 12-coordinate geometry to three equivalent Be(1) and nine equivalent Be(2) atoms.
