Nb Nb Al Te
Nb2AlTe crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Nb2AlTe cluster. There are two inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a single-bond geometry to one Nb(2) atom. The Nb(1)-Nb(2) bond length is 1.29 Å. In the second Nb site, Nb(2) is bonded in a bent 150 degrees geometry to one Nb(1) and one Al(1) atom. The Nb(2)-Al(1) bond length is 1.48 Å. Al(1) is bonded in a distorted single-bond geometry to one Nb(2) and one Te(1) atom. The Al(1)-Te(1) bond length is 0.96 Å. Te(1) is bonded in a single-bond geometry to one Al(1) atom.
