Sr2NbTe crystallizes in the triclinic P1 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 4-coordinate geometry to one Nb(1) and three equivalent Te(1) atoms. The Sr(1)-Nb(1) bond length is 2.08 Å. There is one shorter (2.51 Å) and two longer (3.46 Å) Sr(1)-Te(1) bond lengths. In the second Sr site, Sr(2) is bonded in a single-bond geometry to one Nb(1) and one Te(1) atom. The Sr(2)-Nb(1) bond length is 1.26 Å. The Sr(2)-Te(1) bond length is 3.75 Å. Nb(1) is bonded in a 3-coordinate geometry to one Sr(1), one Sr(2), and one Te(1) atom. The Nb(1)-Te(1) bond length is 2.08 Å. Te(1) is bonded in a 5-coordinate geometry to one Sr(2), three equivalent Sr(1), and one Nb(1) atom.
