INOR 108 |
| A diverse suite of actinyl peroxide structures have recently been synthesized under alkaline conditions. The structural units of these compounds range from isolated clusters to spherical nano-scale clusters containing 20, 24, 28, or 32 actinyl polyhedra. The nanoclusters may be useful precursors for nuclear materials fabrication, and are potential model systems for processes that occur at the nano-scale. Current research is focusing on improving the synthesis approach. The initial synthesis of the nanocluster-containing crystals required slow evaporation of a solution and the resulting crystals are not stable in air. We have used organic compounds, particularly amines and tetramethylammonium cations, to synthesize crystals containing the nanoclusters (with 20 and 24 uranyl polyhedra). Incorporation of organic ligands allows for much faster synthesis of cluster-bearing crystals, and could significantly change the physical and optical properties of the crystals. Structure solution of resulting crystals has revealed that they are inorganic-organic hybrid structures. |
