Ni W W Au
W2NiAu crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one W2NiAu cluster. There are two inequivalent W sites. In the first W site, W(1) is bonded in a single-bond geometry to one Ni(1) atom. The W(1)-Ni(1) bond length is 1.66 Å. In the second W site, W(2) is bonded in a single-bond geometry to one Au(1) atom. The W(2)-Au(1) bond length is 1.82 Å. Ni(1) is bonded in a single-bond geometry to one W(1) and one Au(1) atom. The Ni(1)-Au(1) bond length is 0.16 Å. Au(1) is bonded in a single-bond geometry to one W(2) and one Ni(1) atom.
