Title: Materials Data on SrSiO3 by Materials Project

Abstract

SrSiO3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to eight O2- atoms to form SrO8 hexagonal bipyramids that share corners with two equivalent SrO8 hexagonal bipyramids, corners with two equivalent SiO4 tetrahedra, edges with six equivalent SrO8 hexagonal bipyramids, and edges with four SiO4 tetrahedra. There are a spread of Sr–O bond distances ranging from 2.51–2.75 Å. In the second Sr2+ site, Sr2+ is bonded to eight O2- atoms to form distorted SrO8 hexagonal bipyramids that share corners with two SrO8 hexagonal bipyramids, corners with two SiO4 tetrahedra, edges with six SrO8 hexagonal bipyramids, and edges with four SiO4 tetrahedra. There are a spread of Sr–O bond distances ranging from 2.48–2.78 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 corners with two equivalent SrO8 hexagonal bipyramids, corners with two equivalent SiO4 tetrahedra, and edges with four SrO8 hexagonal bipyramids. There is two shorter (1.61 Å) and two longer (1.69 Å) Si–O bond length. In the second Si4+ site, Si4+ is bonded to four O2- atomsmore » to form SiO4 tetrahedra that share corners with two SrO8 hexagonal bipyramids, corners with two SiO4 tetrahedra, and edges with four SrO8 hexagonal bipyramids. There is two shorter (1.61 Å) and two longer (1.69 Å) Si–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three Sr2+ and one Si4+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to three Sr2+ and one Si4+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Sr2+ and two equivalent Si4+ atoms. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to three Sr2+ and one Si4+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to two Sr2+ and two Si4+ atoms.« less
