Title: Materials Data on Na6Mg(SO4)4 by Materials Project

Abstract

Na6Mg(SO4)4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.34–2.81 Å. In the second Na1+ site, Na1+ is bonded in a 5-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.37–3.05 Å. In the third Na1+ site, Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share a cornercorner with one MgO6 octahedra, corners with four SO4 tetrahedra, an edgeedge with one NaO6 octahedra, and an edgeedge with one SO4 tetrahedra. The corner-sharing octahedral tilt angles are 65°. There are a spread of Na–O bond distances ranging from 2.37–2.54 Å. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with two equivalent NaO6 octahedra and corners with six SO4 tetrahedra. The corner-sharing octahedral tilt angles are 65°. There are a spread of Mg–O bond distances ranging from 2.09–2.12 Å. There are two inequivalent S6+ sites. In the first S6+ site, S6+ is bonded to four O2- atoms to form SO4more » tetrahedra that share corners with two equivalent NaO6 octahedra and corners with two equivalent MgO6 octahedra. The corner-sharing octahedra tilt angles range from 9–61°. There are a spread of S–O bond distances ranging from 1.48–1.51 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share a cornercorner with one MgO6 octahedra, corners with two equivalent NaO6 octahedra, and an edgeedge with one NaO6 octahedra. The corner-sharing octahedra tilt angles range from 14–43°. There are a spread of S–O bond distances ranging from 1.48–1.51 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Mg2+, and one S6+ atom. In the second O2- site, O2- is bonded to three Na1+ and one S6+ atom to form distorted edge-sharing ONa3S tetrahedra. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three Na1+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to four Na1+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to three Na1+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to three Na1+ and one S6+ atom. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to two Na1+, one Mg2+, and one S6+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+, one Mg2+, and one S6+ atom.« less
