BiF3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure consists of four hydrofluoric acid atoms inside a BiF2 framework. In the BiF2 framework, Bi(1) is bonded in a body-centered cubic geometry to eight equivalent F(1) atoms. F(1) is bonded to four equivalent Bi(1) atoms to form a mixture of corner and edge-sharing FBi4 tetrahedra.
