The compound described by BiF3 is alpha bismuth trifluoride structured and crystallizes in the cubic P-43m 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 one F(4), one F(5), three equivalent F(2), and three equivalent F(3) atoms. There are four inequivalent F sites. In the first F site, F(2) is bonded to four equivalent Bi(1) atoms to form a mixture of edge and corner-sharing FBi4 tetrahedra. In the second F site, F(3) is bonded to four equivalent Bi(1) atoms to form a mixture of edge and corner-sharing FBi4 tetrahedra. In the third F site, F(4) is bonded to four equivalent Bi(1) atoms to form a mixture of edge and corner-sharing FBi4 tetrahedra. In the fourth F site, F(5) is bonded to four equivalent Bi(1) atoms to form a mixture of edge and corner-sharing FBi4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
