Materials Data on LiEu3O4 by Materials Project
Abstract
LiEu3O4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four EuO6 octahedra, corners with two equivalent LiO4 tetrahedra, edges with five EuO6 octahedra, and edges with two equivalent EuO7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 3–13°. There are a spread of Li–O bond distances ranging from 1.89–2.07 Å. There are three inequivalent Eu+2.33+ sites. In the first Eu+2.33+ site, Eu+2.33+ is bonded to six O2- atoms to form EuO6 octahedra that share corners with three equivalent EuO6 octahedra, corners with four equivalent EuO7 pentagonal bipyramids, a cornercorner with one LiO4 tetrahedra, edges with four EuO6 octahedra, edges with four equivalent EuO7 pentagonal bipyramids, and edges with two equivalent LiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 37–74°. There are a spread of Eu–O bond distances ranging from 2.36–2.45 Å. In the second Eu+2.33+ site, Eu+2.33+ is bonded to six O2- atoms to form distorted EuO6 octahedra that share corners with three equivalent EuO6 octahedra, corners with four equivalent EuO7 pentagonal bipyramids, corners with three equivalent LiO4 tetrahedra, edges with six EuO6 octahedra, an edgeedge with one EuO7 pentagonalmore »
