Nb As W W
NbW2As crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NbW2As cluster. Nb(1) is bonded in a water-like geometry to one W(2) and one As(1) atom. The Nb(1)-W(2) bond length is 1.49 Å. The Nb(1)-As(1) bond length is 1.47 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a distorted single-bond geometry to one As(1) atom. The W(1)-As(1) bond length is 1.38 Å. In the second W site, W(2) is bonded in a single-bond geometry to one Nb(1) atom. As(1) is bonded in a 2-coordinate geometry to one Nb(1) and one W(1) atom.
