LiSr2Te2 is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LiSr2Te2 clusters. Li(1) is bonded in a single-bond geometry to one Te(1) atom. The Li(1)-Te(1) bond length is 1.41 Å. Sr(1) is bonded in a single-bond geometry to one Te(2) atom. The Sr(1)-Te(2) bond length is 2.18 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a linear geometry to one Li(1) and one Te(2) atom. The Te(1)-Te(2) bond length is 0.75 Å. In the second Te site, Te(2) is bonded in a 3-coordinate geometry to two equivalent Sr(1) and one Te(1) atom.
