Abstract:Two uranium oxide hydrate frameworks (UOHFs) with either Dy3+ or Lu3+ ions, Dy1.36(H2O)6[(UO2)10UO13(OH)4] (UOHF‐Dy) or Lu2(H2O)8[(UO2)10UO14(OH)3] (UOHF‐Lu), were synthesized hydrothermally and characterized with a range of structural and spectroscopic techniques. Although SEM‐EDS analysis confirmed the same atomic ratio of ~5.5 for U:Dy and U:Lu, they displayed different crystal morphologies, needles for UOHF‐Dy in the orthorhombic C2221 space group and plates for UOHF‐Lu in the triclinic P‐1 space group.

“…11 In terms of secondary cations for the synthetic UOH materials, alkali and alkaline earth metal ions dominate. 12–18 However, UOHs with transition metals, 19–22 lead 23 and lanthanide ions 24–26 have also been studied and reported recently.…”
The role of ammonium ions on the formation of uranium oxide hydrate phases has been investigated, with interlayer hydrogen bonding and the inclusion of nitrate anions being revealed.
