Abstract

LiN2H5SO4 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional and consists of four ammonia molecules, four ammonia 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 are a spread of Li–O bond distances ranging from 1.94–1.99 Å. S2- 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 1.48–1.51 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one S2- atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Li1+ and one S2- atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Li1+ and one S2- atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Li1+ and one S2- atom.
