Title: Materials Data on Eu2O3 by Materials Project

Abstract

Eu2O3 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Eu3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Eu–O bond distances ranging from 2.28–2.64 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to six equivalent Eu3+ atoms to form OEu6 octahedra that share corners with twelve equivalent OEu4 tetrahedra, edges with six equivalent OEu6 octahedra, and edges with six equivalent OEu4 tetrahedra. In the second O2- site, O2- is bonded to four equivalent Eu3+ atoms to form OEu4 tetrahedra that share corners with six equivalent OEu6 octahedra, corners with six equivalent OEu4 tetrahedra, edges with three equivalent OEu6 octahedra, and edges with three equivalent OEu4 tetrahedra. The corner-sharing octahedra tilt angles range from 18–56°.
