Materials Data on SrLiPrTeO6 by Materials Project

Abstract

LiSrPrTeO6 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 20–29°. There are a spread of Li–O bond distances ranging from 2.10–2.19 Å. Sr2+ is bonded in a 12-coordinate geometry to eleven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.47–3.12 Å. Pr3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Pr–O bond distances ranging from 2.42–2.89 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 20–29°. There are a spread of Te–O bond distances ranging from 1.93–1.96 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Sr2+, two equivalent Pr3+, and one Te6+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two equivalent Sr2+, one Pr3+, and one Te6+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two equivalent Sr2+, one Pr3+, and one Te6+ atom. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to one Li1+, two equivalent Sr2+, one Pr3+, and one Te6+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two equivalent Sr2+, one Pr3+, and one Te6+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two equivalent Sr2+, one Pr3+, and one Te6+ atom.
