description: SrFe5Bi4O15 is Orthorhombic Perovskite-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. Sr2+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Sr–O bond distances ranging from 2.61–3.24 Å. There are five inequivalent Fe+2.80+ sites. In the first Fe+2.80+ site, Fe+2.80+ is bonded to six O2- atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 1–17°. There are a spread of Fe–O bond distances ranging from 1.90–2.12 Å. In the second Fe+2.80+ site, Fe+2.80+ is bonded to six O2- atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 10–18°. There are a spread of Fe–O bond distances ranging from 1.95–2.12 Å. In the third Fe+2.80+ site, Fe+2.80+ is bonded to six O2- atoms to form distorted corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 6–19°. There are a spread of Fe–O bond distances ranging from 1.90–2.18 Å. In the fourth Fe+2.80+ site, Fe+2.80+ is bonded to six O2- atoms to form corner-sharing FeO6 octahedra.
