Title: Materials Data on Sr2ZrTiO6 by Materials Project

Abstract

SrTiO3(SrZrO3) crystallizes in the tetragonal P4mm space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.64 Å) and four longer (2.88 Å) Sr–O bond lengths. In the second Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with four equivalent SrO12 cuboctahedra, faces with four equivalent SrO12 cuboctahedra, faces with four equivalent ZrO6 octahedra, and faces with four equivalent TiO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.70–2.96 Å. Zr4+ is bonded to six O2- atoms to form distorted ZrO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with four equivalent ZrO6 octahedra, and faces with four equivalent SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–18°. There are a spread of Zr–O bond distances ranging from 2.04–2.31 Å. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent ZrO6 octahedra, corners with four equivalent TiO6 octahedra, and faces with four equivalent SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–8°. There are a spreadmore » of Ti–O bond distances ranging from 1.82–2.12 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to four Sr2+ and two equivalent Ti4+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+ and two equivalent Zr4+ atoms. In the third O2- site, O2- is bonded in a distorted linear geometry to four equivalent Sr2+, one Zr4+, and one Ti4+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to four equivalent Sr2+, one Zr4+, and one Ti4+ atom.« less
