title: Materials Data on La5Fe4NiO15 by Materials Project

description: La5Fe4NiO15 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are five inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 1-coordinate geometry to seven O2- atoms. There are a spread of La–O bond distances ranging from 2.33–2.82 Å. In the second La3+ site, La3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of La–O bond distances ranging from 2.38–2.84 Å. In the third La3+ site, La3+ is bonded in a 1-coordinate geometry to seven O2- atoms. There are a spread of La–O bond distances ranging from 2.36–2.84 Å. In the fourth La3+ site, La3+ is bonded in a 11-coordinate geometry to seven O2- atoms. There are a spread of La–O bond distances ranging from 2.38–2.82 Å. In the fifth La3+ site, La3+ is bonded in a 12-coordinate geometry to seven O2- atoms. There are a spread of La–O bond distances ranging from 2.41–2.84 Å. There are five inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six O2- atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 22–29°. There are a spread of Fe–O bond distances ranging from 2.01–2.06 Å. In the second Fe3+ site, Fe3+ is bonded to six O2- atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 23–29°. There are four shorter (2.02 Å) and two longer (2.05 Å) Fe–O bond lengths. In the third Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six equivalent NiO6 octahedra. The corner-sharing octahedra tilt angles range from 21–27°. There is four shorter (1.99 Å) and two longer (2.00 Å) Fe–O bond length. In the fourth Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with three equivalent FeO6 octahedra and corners with three equivalent NiO6 octahedra. The corner-sharing octahedra tilt angles range from 21–28°. There are a spread of Fe–O bond distances ranging from 1.98–2.07 Å. In the fifth Fe3+ site, Fe3+ is bonded to six O2- atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 22–29°. There are a spread of Fe–O bond distances ranging from 2.01–2.06 Å. Ni3+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six FeO6 octahedra. The corner-sharing octahedra tilt angles range from 21–28°. There are four shorter (2.03 Å) and two longer (2.08 Å) Ni–O bond lengths. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two La3+ and two Fe3+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two La3+ and two Fe3+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent La3+ and two Fe3+ atoms. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two La3+, one Fe3+, and one Ni3+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two La3+, one Fe3+, and one Ni3+ atom. In the sixth O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent La3+, one Fe3+, and one Ni3+ atom. In the seventh O2- site, O2- is bonded in a 5-coordinate geometry to three La3+, one Fe3+, and one Ni3+ atom. In the eighth O2- site, O2- is bonded in a 5-coordinate geometry to three La3+ and two Fe3+ atoms. In the ninth O2- site, O2- is bonded in a 5-coordinate geometry to three La3+ and two Fe3+ atoms. In the tenth O2- site, O2- is bonded in a 5-coordinate geometry to three La3+ and two Fe3+ atoms.
