Title: Materials Data on Na4SiO4 by Materials Project

Abstract

Na4SiO4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to five O2- atoms to form distorted NaO5 trigonal bipyramids that share corners with three equivalent NaO5 square pyramids, corners with two equivalent NaO4 tetrahedra, corners with three equivalent SiO4 tetrahedra, edges with three equivalent NaO5 square pyramids, an edgeedge with one SiO4 tetrahedra, and edges with two equivalent NaO5 trigonal bipyramids. There are a spread of Na–O bond distances ranging from 2.36–2.48 Å. In the second Na1+ site, Na1+ is bonded to five O2- atoms to form distorted NaO5 square pyramids that share a cornercorner with one SiO4 tetrahedra, corners with two equivalent NaO4 tetrahedra, corners with three equivalent NaO5 trigonal bipyramids, edges with two equivalent NaO5 square pyramids, edges with two equivalent SiO4 tetrahedra, and edges with three equivalent NaO5 trigonal bipyramids. There are a spread of Na–O bond distances ranging from 2.36–2.50 Å. In the third Na1+ site, Na1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Na–O bond distances ranging from 2.35–2.45 Å. In the fourth Na1+ site, Na1+ is bonded to fourmore » O2- atoms to form distorted NaO4 tetrahedra that share corners with two equivalent NaO5 square pyramids, corners with four equivalent SiO4 tetrahedra, corners with two equivalent NaO5 trigonal bipyramids, and edges with two equivalent NaO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.29–2.34 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one NaO5 square pyramid, corners with four equivalent NaO4 tetrahedra, corners with three equivalent NaO5 trigonal bipyramids, edges with two equivalent NaO5 square pyramids, and an edgeedge with one NaO5 trigonal bipyramid. There are a spread of Si–O bond distances ranging from 1.65–1.68 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to five Na1+ and one Si4+ atom. In the second O2- site, O2- is bonded to five Na1+ and one Si4+ atom to form distorted edge-sharing ONa5Si octahedra. In the third O2- site, O2- is bonded in a 6-coordinate geometry to five Na1+ and one Si4+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to three Na1+ and one Si4+ atom.« less
