The crystal structure described by BiF3 is Cementite structured and crystallizes in the orthorhombic Pnma space group. Bi(1) is bonded in a 8-coordinate geometry to two equivalent F(2) and six equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Bi(1) atoms. In the second F site, F(1) is bonded in a distorted trigonal planar geometry to three equivalent Bi(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
