Materials Data on Eu2Fe2O5 by Materials Project
Abstract
Eu2Fe2O5 crystallizes in the orthorhombic Ima2 space group. The structure is three-dimensional. Eu2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.31–2.96 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with four equivalent FeO6 octahedra and corners with two equivalent FeO4 tetrahedra. The corner-sharing octahedral tilt angles are 14°. There are a spread of Fe–O bond distances ranging from 1.98–2.10 Å. In the second Fe3+ site, Fe3+ is bonded to four O2- atoms to form FeO4 tetrahedra that share corners with two equivalent FeO6 octahedra and corners with two equivalent FeO4 tetrahedra. The corner-sharing octahedral tilt angles are 33°. There are a spread of Fe–O bond distances ranging from 1.98–2.11 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to four equivalent Eu2+ and two equivalent Fe3+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Eu2+ and two Fe3+ atoms. In the third O2- site, O2- is bonded to two equivalent Eu2+more »
