Al Hg W W
W2HgAl is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one W2HgAl cluster. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 2-coordinate geometry to one Hg(1) and one Al(1) atom. The W(1)-Hg(1) bond length is 1.62 Å. The W(1)-Al(1) bond length is 0.83 Å. In the second W site, W(2) is bonded in a single-bond geometry to one Al(1) atom. The W(2)-Al(1) bond length is 1.24 Å. Hg(1) is bonded in a single-bond geometry to one W(1) atom. Al(1) is bonded in an L-shaped geometry to one W(1) and one W(2) atom.
