Materials Data on LiHSO4 by Materials Project

Abstract

LiHSO4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four equivalent SO4 tetrahedra and an edgeedge with one LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.92–2.02 Å. H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.67 Å) H–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 1.45–1.57 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted T-shaped geometry to two equivalent Li1+ and one S6+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one H1+, and one S6+ atom. In the third O2- site, O2- is bonded in a linear geometry to one Li1+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one H1+ and one S6+ atom.
