The chemistry of uranium. Part XII. Nitrate complexes of uranium(IV) and thorium(IV)

Abstract

The behaviour of [NO₃]^– as anionic ligand towards Th^IV and U^IV in the presence of various amounts of trimethylphosphine and tris (dimethylamino)phosphine oxides has been studied in non-aqueous media by conductometric, spectroscopic, and enthalpimetric methods. The relation between species present in solution and solids isolated and the influence of cation-and neutral-donor ligand size on the action of nitrate as a donor have been investigated.
