Materials Data on Na4B4Sb2SO16 by Materials Project

Abstract

Na4B4Sb2SO16 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a distorted hexagonal planar geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.34–2.53 Å. In the second Na1+ site, Na1+ is bonded in a distorted hexagonal planar geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.34–2.58 Å. B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.38 Å) and one longer (1.39 Å) B–O bond length. Sb5+ is bonded in an octahedral geometry to six O2- atoms. There are four shorter (2.00 Å) and two longer (2.02 Å) Sb–O bond lengths. S6+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All S–O bond lengths are 1.50 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one B3+, and one Sb5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Na1+ and one S6+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one B3+, and one Sb5+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two Na1+, one B3+, and one Sb5+ atom.
