In the title complex, [UO2(NO3)(2)(C11H22N2O)(2)] the central UO22+ cation is centrosymmetrically coordinated by six further O atoms, of which two an from the carbonyl groups of the 1,3-dibutylimidazolidin-2-one ligands and four from the two nitrate anions, forming a distorted hexagonal bipyramidd The average carbonyl U-O bond length is 2.345 (3) Angstrom, which is the shortest value among similar dinitratodioxouranium complexes.
