Materials Data on Na6Mn2B4SO16 by Materials Project

Abstract

Na6Mn2B4SO16 crystallizes in the cubic Fd-3 space group. The structure is three-dimensional. Na1+ is bonded in a distorted hexagonal planar geometry to six O2- atoms. There are two shorter (2.35 Å) and four longer (2.48 Å) Na–O bond lengths. Mn4+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Mn–O bond lengths are 1.95 Å. B3+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All B–O bond lengths are 1.38 Å. S6+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All S–O bond lengths are 1.50 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Na1+, one Mn4+, and one B3+ atom. In the second O2- site, O2- is bonded to three equivalent Na1+ and one S6+ atom to form distorted edge-sharing ONa3S trigonal pyramids.
