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.
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. All Bi(1)-F(1) bond lengths are 2.38 Å. There are two shorter (2.31 Å) and six longer (2.67 Å) Bi(1)-F(2) bond lengths. 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.
