Materials Data on U4BiO10 by Materials Project
U4BiO10 is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. U+4.25+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of U–O bond distances ranging from 2.32–2.35 Å. Bi3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Bi–O bond lengths are 2.43 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent U+4.25+ and one Bi3+ atom to form a mixture of edge and corner-sharing OU3Bi tetrahedra. In the second O2- site, O2- is bonded to four equivalent U+4.25+ atoms to form a mixture of edge and corner-sharing OU4 tetrahedra.
