The material structure described by SrPbF6 crystallizes in the tetragonal P4_2/mmc space group. Sr(1) is bonded in a distorted q6 geometry to two equivalent F(2) and eight equivalent F(1) atoms. Pb(1) is bonded to two equivalent F(3) and four equivalent F(1) atoms to form corner-sharing PbF6 octahedra. The corner-sharing octahedra are not tilted. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one Pb(1) atom. In the second F site, F(2) is bonded in a linear geometry to two equivalent Sr(1) atoms. In the third F site, F(3) is bonded in a linear geometry to two equivalent Pb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
