Nb Sb Sb W
NbWSb2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NbWSb2 cluster. Nb(1) is bonded in a single-bond geometry to one Sb(1) atom. The Nb(1)-Sb(1) bond length is 2.26 Å. W(1) is bonded in a bent 120 degrees geometry to one Sb(1) and one Sb(2) atom. The W(1)-Sb(1) bond length is 1.65 Å. The W(1)-Sb(2) bond length is 1.65 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 2-coordinate geometry to one Nb(1) and one W(1) atom. In the second Sb site, Sb(2) is bonded in a single-bond geometry to one W(1) atom.
