Materials Data on BiF3 by Materials Project

BiF3 is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Bi3+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Bi–F bond distances ranging from 2.28–2.49 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent Bi3+ atoms. In the second F1- site, F1- is bonded in a distorted trigonal planar geometry to three equivalent Bi3+ atoms.

Materials Data on BiF3 by Materials Project

BiF3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Bi3+ is bonded in a distorted body-centered cubic geometry to fourteen F1- atoms. There are eight shorter (2.50 Å) and six longer (2.88 Å) Bi–F bond lengths. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded to four equivalent Bi3+ and four equivalent F1- atoms to form a mixture of face, edge, and corner-sharing FBi4F4 tetrahedra. All F–F bond lengths are 2.50 Å. In the second F1- site, F1- is bonded in a 6-coordinate geometry to six equivalent Bi3+ and eight equivalent F1- atoms.
