The material described by CdF2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. Cd(1) is bonded in a 7-coordinate geometry to three equivalent F(2) and four equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Cd(1) atoms. In the second F site, F(1) is bonded to four equivalent Cd(1) atoms to form a mixture of corner and edge-sharing FCd4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
