Materials Data on Na3UF8 by Materials Project
Na3UF8 is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a body-centered cubic geometry to eight equivalent F1- atoms. All Na–F bond lengths are 2.44 Å. In the second Na1+ site, Na1+ is bonded in a body-centered cubic geometry to eight equivalent F1- atoms. All Na–F bond lengths are 2.44 Å. U5+ is bonded in a body-centered cubic geometry to eight equivalent F1- atoms. All U–F bond lengths are 2.21 Å. F1- is bonded to three Na1+ and one U5+ atom to form a mixture of edge and corner-sharing FNa3U tetrahedra.
