Nb Nb Sb W
Nb2WSb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Nb2WSb cluster. There are two inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a single-bond geometry to one Sb(1) atom. The Nb(1)-Sb(1) bond length is 1.17 Å. In the second Nb site, Nb(2) is bonded in a single-bond geometry to one W(1) atom. The Nb(2)-W(1) bond length is 1.89 Å. W(1) is bonded in a distorted bent 150 degrees geometry to one Nb(2) and one Sb(1) atom. The W(1)-Sb(1) bond length is 1.20 Å. Sb(1) is bonded in a water-like geometry to one Nb(1) and one W(1) atom.
