Materials Data on CsLiSO4 by Materials Project

LiCsSO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cs1+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Cs–O bond distances ranging from 3.23–3.71 Å. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four equivalent SO4 tetrahedra. There is two shorter (1.94 Å) and two longer (1.96 Å) Li–O bond length. S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four equivalent LiO4 tetrahedra. There are a spread of S–O bond distances ranging from 1.48–1.50 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to four equivalent Cs1+, one Li1+, and one S6+ atom. In the second O2- site, O2- is bonded in a linear geometry to three equivalent Cs1+, one Li1+, and one S6+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Cs1+, one Li1+, and one S6+ atom.

LiCsSO4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Cs1+ is bonded in a 3-coordinate geometry to eleven O2- atoms. There are a spread of Cs–O bond distances ranging from 3.11–3.73 Å. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four equivalent SO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.95–1.98 Å. S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four equivalent LiO4 tetrahedra. There is two shorter (1.49 Å) and two longer (1.50 Å) S–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to three equivalent Cs1+, one Li1+, and one S6+ atom. In the second O2- site, O2- is bonded in a linear geometry to three equivalent Cs1+, one Li1+, and one S6+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to three equivalent Cs1+, one Li1+, and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Cs1+, one Li1+, and one S6+ atom.

Materials Data on CsLiSO4 by Materials Project

LiCsSO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cs1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Cs–O bond distances ranging from 2.93–3.23 Å. Li1+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.87 Å) and two longer (1.92 Å) Li–O bond length. S6+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.49 Å) and three longer (1.50 Å) S–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+ and one S6+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Cs1+, one Li1+, and one S6+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cs1+, one Li1+, and one S6+ atom.
