A diverse group of actinyl peroxides have been synthesized under alkaline conditions ranging from isolated clusters to spherical nanoclusters containing 20, 24, 28, or 32 actinyl polyhedra. The addition of organic templating agents has led to the discovery of new techniques for synthesizing the actinyl peroxides as well as novel structures that incorporate organic ligands into the crystal structure. Single crystals of a novel uranyl peroxide have been synthesized at room temperature and the structure has been determined using a Bruker single crystal X-ray diffractometer equipped with the APEX CCD detector. The crystal structure was solved in the cubic space group P23 with a = 17.4847(6)Å. A detailed description of the crystal structure and 1H and 13C NMR spectroscopy will be presented.
