Materials Data on Eu2Co2O5 by Materials Project
Eu2Co2O5 crystallizes in the orthorhombic Ima2 space group. The structure is three-dimensional. Eu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.32–2.89 Å. There are two inequivalent Co2+ sites. In the first Co2+ site, Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with four equivalent CoO6 octahedra and corners with two equivalent CoO4 tetrahedra. The corner-sharing octahedral tilt angles are 14°. There are a spread of Co–O bond distances ranging from 1.95–2.17 Å. In the second Co2+ site, Co2+ is bonded to four O2- atoms to form CoO4 tetrahedra that share corners with two equivalent CoO6 octahedra and corners with two equivalent CoO4 tetrahedra. The corner-sharing octahedral tilt angles are 38°. There are a spread of Co–O bond distances ranging from 1.94–2.03 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to four equivalent Eu3+ and two equivalent Co2+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Eu3+ and two Co2+ atoms. In the third O2- site, O2- is bonded to two equivalent Eu3+ and two equivalent Co2+ atoms to form corner-sharing OEu2Co2 tetrahedra.
