YF3 is Cementite structured and crystallizes in the orthorhombic Pnma space group. Y(1) is bonded in a 9-coordinate geometry to three 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 trigonal planar geometry to three equivalent Y(1) atoms. In the second F site, F(1) is bonded in a distorted trigonal planar geometry to three equivalent Y(1) atoms.
YF3 is Cementite structured and crystallizes in the orthorhombic Pnma space group. Y(1) is bonded in a 9-coordinate geometry to three equivalent F(2) and six equivalent F(1) atoms. There are a spread of Y(1)-F(2) bond distances ranging from 2.30-2.48 Å. There are two shorter (2.29 Å) and four longer (2.30 Å) Y(1)-F(1) 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 Y(1) atoms. In the second F site, F(1) is bonded in a distorted trigonal planar geometry to three equivalent Y(1) atoms.
