Sr2LaTe crystallizes in the triclinic P1 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one Sr(2), one La(1), and one Te(1) atom. The Sr(1)-Sr(2) bond length is 3.23 Å. The Sr(1)-La(1) bond length is 3.23 Å. The Sr(1)-Te(1) bond length is 0.11 Å. In the second Sr site, Sr(2) is bonded in a 6-coordinate geometry to one Sr(1), four equivalent La(1), and one Te(1) atom. There are a spread of Sr(2)-La(1) bond distances ranging from 3.36-3.79 Å. The Sr(2)-Te(1) bond length is 3.66 Å. La(1) is bonded to one Sr(1), four equivalent Sr(2), and one Te(1) atom to form a mixture of distorted corner and edge-sharing LaSr5Te octahedra. The corner-sharing octahedral tilt angles range from 0-7°. The La(1)-Te(1) bond length is 3.66 Å. Te(1) is bonded in a single-bond geometry to one Sr(1), one Sr(2), and one La(1) atom.
