Materials Data on NaErF4 by Materials Project
NaErF4 is Fluorite-derived structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Na1+ is bonded in a body-centered cubic geometry to eight equivalent F1- atoms. All Na–F bond lengths are 2.42 Å. Er3+ is bonded in a body-centered cubic geometry to eight equivalent F1- atoms. All Er–F bond lengths are 2.28 Å. F1- is bonded to two equivalent Na1+ and two equivalent Er3+ atoms to form a mixture of corner and edge-sharing FNa2Er2 tetrahedra.
