The material structure described by LaF3 is beta Cu3Ti structured and crystallizes in the orthorhombic Pmmn space group. La(1) is bonded in a 12-coordinate geometry to four equivalent F(2) and eight equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 4-coordinate geometry to four equivalent La(1) atoms. In the second F site, F(2) is bonded in a distorted see-saw-like geometry to four equivalent La(1) atoms. is represented by the CIF file [CIF]
