Be Be Bi W
Be2WBi crystallizes in the monoclinic Pm space group. Be(1) is bonded in a 5-coordinate geometry to one Be(1), two equivalent W(1), and two equivalent Bi(1) atoms. The Be(1)-Be(1) bond length is 1.28 Å. There is one shorter (2.95 Å) and one longer (3.03 Å) Be(1)-W(1) bond length. There is one shorter (2.74 Å) and one longer (2.88 Å) Be(1)-Bi(1) bond length. W(1) is bonded in a single-bond geometry to four equivalent Be(1) and one Bi(1) atom. The W(1)-Bi(1) bond length is 0.81 Å. Bi(1) is bonded in a single-bond geometry to four equivalent Be(1) and one W(1) atom.
