Materials Data on LiH4SNO4 by Materials Project

LiNH4SO4 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional and consists of four ammonium molecules and one LiSO4 framework. In the LiSO4 framework, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four equivalent SO4 tetrahedra. There is two shorter (1.95 Å) and two longer (1.97 Å) Li–O bond length. S2- is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four equivalent LiO4 tetrahedra. There is two shorter (1.48 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 bent 150 degrees geometry to one Li1+ and one S2- atom. In the second O2- site, O2- is bonded in a linear geometry to one Li1+ and one S2- atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Li1+ and one S2- atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one S2- atom.

LiNH4SO4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of eight ammonium 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 1.91–1.97 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 are a spread of Li–O bond distances ranging from 1.94–1.98 Å. There are two inequivalent S2- sites. In the first S2- site, S2- 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 1.48–1.50 Å. In the second S2- site, S2- 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 1.47–1.50 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Li1+ and one S2- atom.

Materials Data on LiH4SNO4 by Materials Project

LiNH4SO4 crystallizes in the orthorhombic Pca2_1 space group. The structure is two-dimensional and consists of eight ammonium molecules and two LiSO4 sheets oriented in the (0, 0, 1) direction. In each LiSO4 sheet, 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 two equivalent LiO4 tetrahedra and corners with four SO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.97–2.00 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent LiO4 tetrahedra and corners with four SO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.97–2.00 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four LiO4 tetrahedra. There is one shorter (1.48 Å) and three longer (1.50 Å) S–O bond length. In the second S2- site, S2- is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four LiO4 tetrahedra. There is one shorter (1.48 Å) and three longer (1.50 Å) S–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one S2- atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one S2- atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one S2- atom. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to two Li1+ and one S2- atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one S2- atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one S2- atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one S2- atom. In the eighth O2- site, O2- is bonded in a trigonal planar geometry to two Li1+ and one S2- atom.
