NaErF4 is Fluorite-derived structured and crystallizes in the tetragonal I4_1/amd space group. Na(1) is bonded in a body-centered cubic geometry to eight equivalent F(1) atoms. Er(1) is bonded in a body-centered cubic geometry to eight equivalent F(1) atoms. F(1) is bonded to two equivalent Na(1) and two equivalent Er(1) atoms to form a mixture of edge and corner-sharing FNa2Er2 tetrahedra.
