UF3 crystallizes in the trigonal P-3m1 space group. U(1) is bonded in a body-centered cubic geometry to two equivalent F(2) and six equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to three equivalent U(1) atoms. In the second F site, F(2) is bonded in a linear geometry to two equivalent U(1) atoms.
UF3 crystallizes in the trigonal P-3m1 space group. U(1) is bonded in a body-centered cubic geometry to two equivalent F(2) and six equivalent F(1) atoms. Both U(1)-F(2) bond lengths are 2.32 Å. All U(1)-F(1) bond lengths are 2.46 Å. There are two inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to three equivalent U(1) atoms. In the second F site, F(2) is bonded in a linear geometry to two equivalent U(1) atoms.
