Materials Data on Li2SO4 by Materials Project

Abstract

Li2SO4 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.99–2.17 Å. In the second Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.97–2.56 Å. In the third Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.97–2.13 Å. In the fourth Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 2.02–2.14 Å. There are two inequivalent S6+ sites. In the first S6+ site, S6+ is bonded in a tetrahedral geometry to four O2- atoms. All S–O bond lengths are 1.49 Å. In the second S6+ site, S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.48–1.50 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted T-shaped geometry to two Li1+ and one S6+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Li1+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted T-shaped geometry to two Li1+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted T-shaped geometry to two Li1+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a distorted T-shaped geometry to two Li1+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted T-shaped geometry to two Li1+ and one S6+ atom. In the seventh O2- site, O2- is bonded in a distorted T-shaped geometry to two Li1+ and one S6+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to three Li1+ and one S6+ atom.
