Materials Data on LiSNO4 by Materials Project

Abstract

(LiSO4)2N2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional and consists of four ammonia molecules and one LiSO4 framework. In the LiSO4 framework, there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four SO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.94–1.97 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four SO4 tetrahedra. There is three shorter (1.96 Å) and one longer (1.97 Å) Li–O bond length. There are two inequivalent S6+ sites. In the first S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four LiO4 tetrahedra. There are a spread of S–O bond distances ranging from 1.47–1.49 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four LiO4 tetrahedra. There is two shorter (1.48 Å) and two longer (1.49 Å) S–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Li1+ and one S6+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Li1+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Li1+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Li1+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a linear geometry to one Li1+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Li1+ and one S6+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one S6+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one S6+ atom.
