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.
