Dinitratodioxo[3-(triphenyl­phosphonio)propionato]uranium(VI)

The U atom in the crystal structure of the title compound, [U(NO₃)₂O₂(C₂₁H₁₉O₂P)], shows hexa­gonal-bipyramidal coordination, as the nitrate and carboxyl­ate groups function as chelates. The oxo O atoms occupy the axial sites of this uncommon coordination geometry.
