Title: Materials Data on Ba4TiSi12(SnO12)3 by Materials Project

Abstract

Ba4TiSi12(SnO12)3 crystallizes in the trigonal P312 space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.78 Å) and three longer (2.79 Å) Ba–O bond lengths. In the second Ba2+ site, Ba2+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Ba–O bond lengths are 2.78 Å. In the third Ba2+ site, Ba2+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Ba–O bond lengths are 2.85 Å. Ti4+ is bonded to six equivalent O2- atoms to form TiO6 octahedra that share corners with six equivalent SiO4 tetrahedra. All Ti–O bond lengths are 1.98 Å. There are two inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six SiO4 tetrahedra. All Sn–O bond lengths are 2.07 Å. In the second Sn4+ site, Sn4+ is bonded to six equivalent O2- atoms to form SnO6 octahedra that share corners with six equivalent SiO4 tetrahedra. All Sn–O bond lengths are 2.06 Å. There are two inequivalent Si4+ sites. In the firstmore » Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two SnO6 octahedra and corners with two equivalent SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 45–46°. There are a spread of Si–O bond distances ranging from 1.63–1.66 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one TiO6 octahedra, a cornercorner with one SnO6 octahedra, and corners with two equivalent SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 41–46°. There is two shorter (1.63 Å) and two longer (1.66 Å) Si–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Si4+ atoms. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Si4+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Ba2+, one Sn4+, and one Si4+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Ba2+, one Sn4+, and one Si4+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Ba2+, one Sn4+, and one Si4+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one Ba2+, one Ti4+, and one Si4+ atom.« less
