Title: Materials Data on SrTiFe4Bi4O15 by Materials Project

Abstract

SrTiFe4Bi4O15 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. Sr2+ is bonded to twelve O2- atoms to form distorted SrO12 cuboctahedra that share corners with two equivalent SrO12 cuboctahedra, faces with two equivalent SrO12 cuboctahedra, faces with four equivalent TiO6 octahedra, and faces with four equivalent FeO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.67–3.20 Å. Ti4+ is bonded to six O2- atoms to form distorted TiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with four equivalent FeO6 octahedra, and faces with four equivalent SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 5–15°. There are a spread of Ti–O bond distances ranging from 1.81–2.26 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six O2- atoms to form distorted FeO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with four FeO6 octahedra, and faces with two equivalent SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 10–18°. There are a spread of Fe–O bond distances ranging from 1.94–2.18 Å. In the second Fe3+ site, Fe3+ is bonded to six O2- atoms to form distorted corner-sharingmore » FeO6 octahedra. The corner-sharing octahedra tilt angles range from 16–18°. There are a spread of Fe–O bond distances ranging from 1.96–2.15 Å. There are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 9-coordinate geometry to three O2- atoms. There are a spread of Bi–O bond distances ranging from 2.20–2.25 Å. In the second Bi3+ site, Bi3+ is bonded in a 9-coordinate geometry to three O2- atoms. There are a spread of Bi–O bond distances ranging from 2.20–2.23 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Sr2+ and two equivalent Ti4+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Fe3+ and one Bi3+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two Fe3+ and one Bi3+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Fe3+ and one Bi3+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Sr2+, one Ti4+, and one Fe3+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+, one Ti4+, one Fe3+, and one Bi3+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+, two equivalent Fe3+, and one Bi3+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Fe3+ and one Bi3+ atom.« less
