The material described by BiF4BiF6 is alpha structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one trifluorobismuthane;hydrofluoride molecule and one BiF6 cluster. In the BiF6 cluster, Bi(2) is bonded in a 6-coordinate geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(5) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one Bi(2) atom. In the second F site, F(2) is bonded in a single-bond geometry to one Bi(2) atom. In the third F site, F(5) is bonded in a single-bond geometry to one Bi(2) atom. is represented by the CIF file [CIF]
