Materials Data on MnH6SO6 by Materials Project
MnH6SO6 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is one-dimensional and consists of two MnH6SO6 ribbons oriented in the (1, 0, 0) direction. Mn2+ is bonded in a 7-coordinate geometry to one H1+ and six O2- atoms. The Mn–H bond length is 2.31 Å. There are a spread of Mn–O bond distances ranging from 2.14–2.52 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one Mn2+ and one O2- atom. The H–O bond length is 1.00 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. S4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.55 Å) and one longer (1.56 Å) S–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn2+ and one S4+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Mn2+ and one S4+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn2+ and one S4+ atom. In the fourth O2- site, O2- is bonded in a water-like geometry to one Mn2+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one Mn2+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a distorted water-like geometry to one Mn2+ and two H1+ atoms.
