Materials Data on LiEuF2 by Materials Project

LiEuF2 crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. Li is bonded in a square co-planar geometry to four equivalent F atoms. There are two shorter (2.32 Å) and two longer (2.34 Å) Li–F bond lengths. Eu is bonded to six equivalent F atoms to form edge-sharing EuF6 octahedra. There are a spread of Eu–F bond distances ranging from 2.51–2.54 Å. F is bonded to two equivalent Li and three equivalent Eu atoms to form a mixture of distorted edge and corner-sharing FLi2Eu3 trigonal bipyramids.

Materials Data on LiEuF2 by Materials Project

LiEuF2 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional and consists of two LiEuF2 frameworks. Li is bonded in a linear geometry to two equivalent F atoms. Both Li–F bond lengths are 1.86 Å. Eu is bonded in a distorted rectangular see-saw-like geometry to four equivalent F atoms. All Eu–F bond lengths are 2.49 Å. F is bonded in a distorted trigonal non-coplanar geometry to one Li and two equivalent Eu atoms.
