Materials Data on MnH4(SO5)2 by Materials Project

Abstract

MnH4(SO5)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Mn4+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with four equivalent SO4 tetrahedra. All Mn–O bond lengths are 1.96 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.66 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.63 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 41–47°. There are a spread of S–O bond distances ranging from 1.45–1.53 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one H1+ and one S6+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Mn4+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Mn4+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Mn4+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one H1+ and one S6+ atom.
