Materials Data on Li2MnH4(SO5)2 by Materials Project

Abstract

Li2MnH4(SO5)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 2.04–2.50 Å. Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with four equivalent SO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 2.18–2.21 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.73 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.70 Å) H–O bond length. S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 44–50°. There are a spread of S–O bond distances ranging from 1.47–1.51 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Li1+, one H1+, and one S6+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Mn2+, and one S6+ atom. In the third O2- site, O2- is bonded in a distorted water-like geometry to one Li1+, one Mn2+, and two H1+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Mn2+, and one S6+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one H1+, and one S6+ atom.
