description: Sr3La2FeCo4O15 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are three inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with three equivalent LaO12 cuboctahedra, corners with nine SrO12 cuboctahedra, faces with three equivalent SrO12 cuboctahedra, faces with three equivalent LaO12 cuboctahedra, faces with three equivalent FeO6 octahedra, and faces with five CoO6 octahedra. There are six shorter (2.74 Å) and six longer (2.78 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 three equivalent LaO12 cuboctahedra, corners with nine SrO12 cuboctahedra, faces with three equivalent SrO12 cuboctahedra, faces with three equivalent LaO12 cuboctahedra, a faceface with one FeO6 octahedra, and faces with seven CoO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.73–2.79 Å. In the third Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with twelve SrO12 cuboctahedra, faces with six LaO12 cuboctahedra, a faceface with one FeO6 octahedra, and faces with seven CoO6 octahedra. There are three shorter (2.72 Å) and nine longer (2.74 Å) Sr–O bond lengths. There are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share corners with three equivalent SrO12 cuboctahedra, corners with nine LaO12 cuboctahedra, faces with six SrO12 cuboctahedra, and faces with eight CoO6 octahedra. There are a spread of La–O bond distances ranging from 2.63–2.74 Å. In the second La3+ site, La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share corners with three equivalent SrO12 cuboctahedra, corners with nine LaO12 cuboctahedra, faces with six SrO12 cuboctahedra, faces with three equivalent FeO6 octahedra, and faces with five CoO6 octahedra. There are a spread of La–O bond distances ranging from 2.67–2.77 Å. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six CoO6 octahedra, faces with three equivalent LaO12 cuboctahedra, and faces with five SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 1–3°. There is three shorter (1.96 Å) and three longer (1.99 Å) Fe–O bond length. There are four inequivalent Co+3.75+ sites. In the first Co+3.75+ site, Co+3.75+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with three equivalent FeO6 octahedra, corners with three equivalent CoO6 octahedra, faces with two LaO12 cuboctahedra, and faces with six SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 3–6°. There is three shorter (1.90 Å) and three longer (1.94 Å) Co–O bond length. In the second Co+3.75+ site, Co+3.75+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six CoO6 octahedra, faces with three equivalent LaO12 cuboctahedra, and faces with five SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 1–6°. There is three shorter (1.91 Å) and three longer (1.97 Å) Co–O bond length. In the third Co+3.75+ site, Co+3.75+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six CoO6 octahedra, faces with four SrO12 cuboctahedra, and faces with four LaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 1–2°. There is three shorter (1.93 Å) and three longer (1.95 Å) Co–O bond length. In the fourth Co+3.75+ site, Co+3.75+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with three equivalent FeO6 octahedra, corners with three equivalent CoO6 octahedra, faces with four SrO12 cuboctahedra, and faces with four LaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 1–2°. There is three shorter (1.90 Å) and three longer (1.93 Å) Co–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to two equivalent Sr2+, two La3+, and two Co+3.75+ atoms. In the second O2- site, O2- is bonded in a distorted linear geometry to three Sr2+, one La3+, and two Co+3.75+ atoms. In the third O2- site, O2- is bonded in a distorted linear geometry to two Sr2+, two equivalent La3+, and two Co+3.75+ atoms. In the fourth O2- site, O2- is bonded in a distorted linear geometry to three Sr2+, one La3+, one Fe3+, and one Co+3.75+ atom. In the fifth O2- site, O2- is bonded in a distorted linear geometry to two Sr2+, two equivalent La3+, one Fe3+, and one Co+3.75+ atom.
