The material structure described by PbF2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. Pb(1) is bonded in a 7-coordinate geometry to three equivalent F(1) and four equivalent F(2) atoms. There are two inequivalent F sites. In the first F site, F(2) is bonded to four equivalent Pb(1) atoms to form a mixture of corner and edge-sharing FPb4 tetrahedra. In the second F site, F(1) is bonded in a trigonal non-coplanar geometry to three equivalent Pb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
