Nb Te Te Pb
NbPbTe2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NbPbTe2 cluster. Nb(1) is bonded in a 2-coordinate geometry to one Te(1) and one Te(2) atom. The Nb(1)-Te(1) bond length is 2.06 Å. The Nb(1)-Te(2) bond length is 1.57 Å. Pb(1) is bonded in a 2-coordinate geometry to one Te(1) and one Te(2) atom. The Pb(1)-Te(1) bond length is 1.57 Å. The Pb(1)-Te(2) bond length is 2.06 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted L-shaped geometry to one Nb(1) and one Pb(1) atom. In the second Te site, Te(2) is bonded in a distorted single-bond geometry to one Nb(1) and one Pb(1) atom.
