The crystal structure described by NaCaYCdF8 is Fluorite-derived structured and crystallizes in the tetragonal I-4m2 space group. Na(1) is bonded in a body-centered cubic geometry to eight equivalent F(1) atoms. Ca(1) is bonded in a body-centered cubic geometry to eight equivalent F(1) atoms. Y(1) is bonded in a body-centered cubic geometry to eight equivalent F(1) atoms. Cd(1) is bonded in a body-centered cubic geometry to eight equivalent F(1) atoms. F(1) is bonded to one Na(1), one Ca(1), one Y(1), and one Cd(1) atom to form a mixture of corner and edge-sharing FNaCaYCd tetrahedra. is represented by the CIF file [CIF]
