Nb Bi W W
NbW2Bi is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NbW2Bi cluster. Nb(1) is bonded in an L-shaped geometry to one W(1) and one Bi(1) atom. The Nb(1)-W(1) bond length is 0.42 Å. The Nb(1)-Bi(1) bond length is 0.42 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a single-bond geometry to one Nb(1) atom. In the second W site, W(2) is bonded in a 1-coordinate geometry to one Bi(1) atom. The W(2)-Bi(1) bond length is 0.93 Å. Bi(1) is bonded in a distorted single-bond geometry to one Nb(1) and one W(2) atom.
