Nitrate complexes of the actinide elements are known to play an important role in the separation chemistry of some elements. While tetravalent actinides were known to form hexanitrates in high nitric acid concentrations, no structural information on these complexes was available in the literature until the structure of bis(tetraethylammonium) hexanitratouranium(IV) was reported in 1988. In an effort to understand and improve the existing separation processes, novel hexanitrato complexes of plutonium and thorium were synthesised and characterised by three-dimensional X-ray diffraction.
