Title: Materials Data on K2SiO3 by Materials Project

Abstract

K2SiO3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are six inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of K–O bond distances ranging from 2.74–3.24 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.72–3.30 Å. In the third K1+ site, K1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of K–O bond distances ranging from 2.62–2.89 Å. In the fourth K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.64–3.08 Å. In the fifth K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.60–2.87 Å. In the sixth K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.79–3.26 Å. There are three inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bondedmore » to four O2- atoms to form corner-sharing SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.70 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form corner-sharing SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.70 Å. In the third Si4+ site, Si4+ is bonded to four O2- atoms to form corner-sharing SiO4 tetrahedra. There is two shorter (1.62 Å) and two longer (1.70 Å) Si–O bond length. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to five K1+ and one Si4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to five K1+ and one Si4+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two K1+ and two Si4+ atoms. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to four K1+ and one Si4+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to five K1+ and one Si4+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to five K1+ and one Si4+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to two K1+ and two Si4+ atoms. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to four K1+ and one Si4+ atom. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to two K1+ and two Si4+ atoms.« less
