SmF3 is Cementite structured and crystallizes in the orthorhombic Pnma space group. Sm(1) is bonded in a 9-coordinate geometry to three equivalent F(1) and six equivalent F(2) atoms. There are two inequivalent F sites. In the first F site, F(2) is bonded in a distorted trigonal planar geometry to three equivalent Sm(1) atoms. In the second F site, F(1) is bonded in a distorted trigonal planar geometry to three equivalent Sm(1) atoms.
