The crystal structure described by NaErF4 is Fluorite-derived structured and crystallizes in the tetragonal P4/mmm 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 corner and edge-sharing FNa2Er2 tetrahedra. is represented by the CIF card [CIF]
