Title: Materials Data on Na2MgH20(SO9)2 by Materials Project

Abstract

Mg(H2O)6(NaH4SO6)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of two magnesium;hexahydrate molecules and one NaH4SO6 sheet oriented in the (0, 0, 1) direction. In the NaH4SO6 sheet, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.40–2.60 Å. There are four 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 0.98 Å. In the second 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 third 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 fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. S6+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.49 Å) and three longer (1.50 Å) S–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to twomore » equivalent Na1+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to two equivalent Na1+ and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Na1+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one S6+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Na1+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one S6+ atom.« less
