DyF3 crystallizes in the trigonal P-3c1 space group. Dy(1) is bonded in a 9-coordinate geometry to one F(1), two equivalent F(2), and six equivalent F(3) atoms. There are three inequivalent F sites. In the first F site, F(2) is bonded in a trigonal planar geometry to three equivalent Dy(1) atoms. In the second F site, F(3) is bonded in a 3-coordinate geometry to three equivalent Dy(1) atoms. In the third F site, F(1) is bonded in a trigonal planar geometry to three equivalent Dy(1) atoms.
