Materials Data on SrLiEuTeO6 by Materials Project

LiSrEuTeO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic Pc space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six equivalent TeO6 octahedra. The corner-sharing octahedra tilt angles range from 23–31°. There are a spread of Li–O bond distances ranging from 2.12–2.27 Å. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.52–2.78 Å. Eu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.39–2.77 Å. Te6+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with six equivalent LiO6 octahedra. The corner-sharing octahedra tilt angles range from 23–31°. There is four shorter (1.95 Å) and two longer (1.96 Å) Te–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, one Sr2+, one Eu3+, and one Te6+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to one Li1+, one Sr2+, two equivalent Eu3+, and one Te6+ atom. In the third O2- site, O2- is bonded in a 5-coordinate geometry to one Li1+, one Sr2+, two equivalent Eu3+, and one Te6+ atom. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to one Li1+, two equivalent Sr2+, one Eu3+, and one Te6+ atom. In the fifth O2- site, O2- is bonded in a 5-coordinate geometry to one Li1+, two equivalent Sr2+, one Eu3+, and one Te6+ atom. In the sixth O2- site, O2- is bonded in a distorted tetrahedral geometry to one Li1+, one Sr2+, one Eu3+, and one Te6+ atom.
