Abstract:
The synthesis, structure, and properties of the first anionic bimetallic NpCs MOF are reported. The structure of the obtained compound is based on a novel type of secondary building unit (SBU) - a Np4Cs2O8 cluster. The SBU contains a set of cation-cation interactions: NpO⋯Np, Np⋯Cs, and Cs⋯Cs. The micropores of the new material were found to be too small to facilitate the sorption and ion exchange of 137Cs. The limiting pore size of the framework is 2.69 Å. The synthesized material is stable up to 400 °C, stable during hydrolysis and does not deteriorate at doses of at least 6 MGy. The NpCs MOF may be of interest for the separation of gases with small atom sizes, such as hydrogen isotopes and light noble gases.
