DyF3 is Cementite structured and crystallizes in the orthorhombic Pnma space group. Dy(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 Dy(1) atoms. In the second F site, F(1) is bonded in a distorted trigonal planar geometry to three equivalent Dy(1) atoms.
DyF3 is Cementite structured and crystallizes in the orthorhombic Pnma space group. Dy(1) is bonded in a 9-coordinate geometry to three equivalent F(1) and six equivalent F(2) atoms. There are a spread of Dy(1)-F(1) bond distances ranging from 2.29-2.48 Å. There are four shorter (2.29 Å) and two longer (2.30 Å) Dy(1)-F(2) bond lengths. There are two inequivalent F sites. In the first F site, F(2) is bonded in a distorted trigonal planar geometry to three equivalent Dy(1) atoms. In the second F site, F(1) is bonded in a distorted trigonal planar geometry to three equivalent Dy(1) atoms.
