LiSr2Te crystallizes in the monoclinic Cm space group. Li(1) is bonded in a 3-coordinate geometry to one Sr(1), one Sr(2), and one Te(1) atom. The Li(1)-Sr(1) bond length is 2.82 Å. The Li(1)-Sr(2) bond length is 2.91 Å. The Li(1)-Te(1) bond length is 3.37 Å. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 1-coordinate geometry to one Li(1) and two equivalent Te(1) atoms. There is one shorter (3.04 Å) and one longer (3.85 Å) Sr(1)-Te(1) bond length. In the second Sr site, Sr(2) is bonded in a distorted single-bond geometry to one Li(1) and three equivalent Te(1) atoms. There is one shorter (2.89 Å) and two longer (3.82 Å) Sr(2)-Te(1) bond lengths. Te(1) is bonded in a 6-coordinate geometry to one Li(1), two equivalent Sr(1), and three equivalent Sr(2) atoms.
