      abstract     = {Herein, we have synthesised a novel uranium oxyhydroxide
                      (UOH) phase, Rb2K2[(UO2)6O4(OH)6]·(IO3)2, under
                      hydrothermal conditions which intercalates IO3− via a
                      hybrid salt-inclusion and host–guest mechanism. The
                      mechanism is based on favorable intermolecular bonding
                      between disordered Rb+/K+ and IO3− ions and hydroxyl and
                      layer void positions respectively. To examine whether the
                      intercalation may occur ubiquitously for UOH phases, the
                      known UOH mineral phases metaschoepite
                      ([(UO2)8O2(OH)12]·12H2O), compreignacite
                      (K2[(UO2)6O4(OH)6]·7H2O) and also related β-UO2(OH)2 were
                      synthesised and exposed to aqueous I− and IO3− for 1
                      month statically at RT and 60 °C in air and the solid
                      analysed using laser ablation inductively coupled plasma
                      mass spectroscopy. Measurements indicate intercalation can
                      occur homogeneously, but the affinity is dependent upon the
                      structure of the UOH phases and temperature, where higher
                      temperatures and when the interlayer space is free of
                      initial moieties are favoured. It was also found that after
                      repeated washing of the UOH samples with DI water the
                      intercalated iodine was retained. UOH phases are known to
                      form during the oxidative corrosion of spent nuclear fuel
                      during an accident scenario in the near field, this work
                      suggests they may help retard the transport of radiolytic
                      iodine into the environment during a long-term release
                      event.},
