The material structure described by BiF3 is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. Bi(1) is bonded to three equivalent F(1) and eight equivalent F(2) atoms to form a mixture of distorted face and edge-sharing BiF11 trigonal bipyramids. There are two inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to three equivalent Bi(1) atoms. In the second F site, F(2) is bonded in a distorted single-bond geometry to four equivalent Bi(1) atoms. is represented by the CIF card [CIF]
