Materials Data on NaPH4SO8 by Materials Project
NaPH4SO8 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Na1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Na–O bond distances ranging from 2.36–2.87 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.52–1.58 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.60 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.62 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.61 Å) H–O bond length. In the fourth H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.68 Å) H–O bond length. S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.46–1.58 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Na1+, one P5+, and one H1+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one Na1+, one P5+, and two H1+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Na1+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Na1+ and one S6+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+, one H1+, and one S6+ atom. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to two H1+ and one S6+ atom.
