The material described by LiEuF2 crystallizes in the tetragonal I4_1/amd space group. Li(1) is bonded in a square co-planar geometry to four equivalent F(1) atoms. Eu(1) is bonded to six equivalent F(1) atoms to form edge-sharing EuF6 octahedra. F(1) is bonded to two equivalent Li(1) and three equivalent Eu(1) atoms to form a mixture of distorted corner and edge-sharing FLi2Eu3 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
