Materials Data on LiHSeO3 by Materials Project
LiHSeO3 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form corner-sharing LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.96–2.05 Å. H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.60 Å) H–O bond length. Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.69–1.84 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one H1+, and one Se4+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Li1+ and one Se4+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one H1+, and one Se4+ atom.
