Title: Materials Data on Na3Si2PO8 by Materials Project

Abstract

Na3Si2PO8 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of Na–O bond distances ranging from 2.21–2.35 Å. In the second Na1+ site, Na1+ is bonded in a distorted trigonal planar geometry to three O2- atoms. There are a spread of Na–O bond distances ranging from 2.20–2.34 Å. In the third Na1+ site, Na1+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Na–O bond distances ranging from 2.25–2.37 Å. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one SiO4 tetrahedra and a cornercorner with one PO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.59–1.74 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one SiO4 tetrahedra and an edgeedge with one PO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.56–1.76 Å. P5+ ismore » bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one SiO4 tetrahedra and an edgeedge with one SiO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.62 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Si4+, and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Na1+ and one P5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two Na1+ and one Si4+ atom. In the fourth O2- site, O2- is bonded in an L-shaped geometry to one Si4+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Si4+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted see-saw-like geometry to three Na1+ and one Si4+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two Na1+ and one Si4+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Si4+ atoms.« less
