Title: Materials Data on NaAlSiO4 by Materials Project

Abstract

NaAlSiO4 crystallizes in the hexagonal P6_1 space group. The structure is three-dimensional. there are four inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.33–2.67 Å. In the second Na1+ site, Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.39–3.02 Å. In the third Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.32–2.96 Å. In the fourth Na1+ site, Na1+ is bonded in a 2-coordinate geometry to two O2- atoms. There are one shorter (2.37 Å) and one longer (2.40 Å) Na–O bond lengths. There are four inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with four SiO4 tetrahedra.

In the thirteenth O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+, one Al3+, and one Si4+ atom. In the fourteenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Na1+, one Al3+, and one Si4+ atom. In the fifteenth O2- site, O2- is bonded in a distorted linear geometry to one Na1+, one Al3+, and one Si4+ atom.
