Y Be Be W
Be2YW crystallizes in the triclinic P1 space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a 5-coordinate geometry to one Be(2), two equivalent Y(1), and two equivalent W(1) atoms. The Be(1)-Be(2) bond length is 1.88 Å. There is one shorter (2.65 Å) and one longer (2.91 Å) Be(1)-Y(1) bond length. There is one shorter (2.85 Å) and one longer (3.09 Å) Be(1)-W(1) bond length. In the second Be site, Be(2) is bonded in a 5-coordinate geometry to one Be(1), two equivalent Y(1), and two equivalent W(1) atoms. There is one shorter (2.85 Å) and one longer (3.09 Å) Be(2)-Y(1) bond length. There is one shorter (2.65 Å) and one longer (2.91 Å) Be(2)-W(1) bond length. Y(1) is bonded in a single-bond geometry to two equivalent Be(1), two equivalent Be(2), and one W(1) atom. The Y(1)-W(1) bond length is 0.41 Å. W(1) is bonded in a single-bond geometry to two equivalent Be(1), two equivalent Be(2), and one Y(1) atom.
