Title: Materials Data on Ba2Sm2Fe4O11 by Materials Project

Abstract

Ba2Sm2Fe4O11 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form distorted BaO12 cuboctahedra that share corners with four equivalent BaO12 cuboctahedra, faces with four equivalent BaO12 cuboctahedra, faces with four equivalent FeO6 octahedra, and faces with four equivalent FeO5 trigonal bipyramids. There are a spread of Ba–O bond distances ranging from 2.82–3.22 Å. Sm3+ is bonded in a distorted q6 geometry to ten O2- atoms. There are a spread of Sm–O bond distances ranging from 2.56–2.70 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to five O2- atoms to form FeO5 trigonal bipyramids that share corners with three equivalent FeO6 octahedra, corners with two equivalent FeO5 trigonal bipyramids, and faces with four equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–18°. There are a spread of Fe–O bond distances ranging from 1.95–2.04 Å. In the second Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with three equivalent FeO6 octahedra, corners with three equivalent FeO5 trigonal bipyramids, and faces with four equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–6°. Theremore » are a spread of Fe–O bond distances ranging from 1.94–2.11 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ba2+, two equivalent Sm3+, and two Fe3+ atoms. In the second O2- site, O2- is bonded to four equivalent Ba2+ and two Fe3+ atoms to form a mixture of distorted edge and corner-sharing OBa4Fe2 octahedra. The corner-sharing octahedral tilt angles are 0°. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Ba2+, two equivalent Sm3+, and two equivalent Fe3+ atoms. In the fourth O2- site, O2- is bonded in a 6-coordinate geometry to two equivalent Ba2+, two equivalent Sm3+, and two equivalent Fe3+ atoms. In the fifth O2- site, O2- is bonded in a distorted linear geometry to four equivalent Sm3+ and two equivalent Fe3+ atoms.« less
