Neutron diffraction study of β-uranium pentafluoride between 77 and 403 K
Abstract
The structure of β-UF 5 has been refined by neutron powder profile analyses at 77, 293, 348, and 403 K. The structure is relatively temperature insensitive within this range and at 403 K there is a slow conversion to α-UF 5. The coordination polyhedron may be described as either a square antiprism or a dodecahedron, the former polyhedron giving the better fit with the observed atomic positions.
