Title: Materials Data on SrY2Si3O10 by Materials Project

Abstract

SrY2(Si3O10) crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.52–2.92 Å. There are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Y–O bond distances ranging from 2.24–2.60 Å. In the second Y3+ site, Y3+ is bonded to six O2- atoms to form YO6 octahedra that share corners with six SiO4 tetrahedra. There are a spread of Y–O bond distances ranging from 2.20–2.37 Å. There are three 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 YO6 octahedra and a cornercorner with one SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 65°. There are a spread of Si–O bond distances ranging from 1.61–1.69 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent YO6 octahedra and corners with two SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 45–65°. There ismore » one shorter (1.63 Å) and three longer (1.65 Å) Si–O bond length. In the third Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with three equivalent YO6 octahedra and a cornercorner with one SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 51–54°. There are a spread of Si–O bond distances ranging from 1.63–1.67 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Sr2+, one Y3+, and one Si4+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three Y3+ and one Si4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Sr2+, two equivalent Y3+, and one Si4+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Sr2+ and two Si4+ atoms. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+, one Y3+, and one Si4+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one Sr2+, two Y3+, and one Si4+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Si4+ atoms. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Sr2+, one Y3+, and one Si4+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Sr2+, one Y3+, and one Si4+ atom. In the tenth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Y3+ and one Si4+ atom.« less
