  Interaction of U(VI), Np(VI), Pu(VI), and Np(V) with benzenetricarboxylic acids: Complexation in aqueous solutions, synthesis, and crystal structure of uranyl complexes [UO2(H2O)2{C6H3(COO)2(COOH)}]2·2H2O and [(UO2)3(H2O)4{C6H3(COO)3}2]

  摘要：

  The complexation of U(VI), Np(VI), and Pu(VI) and of Np(V) with 1,2,3- and 1,2,4-benzenetricarboxylic acids (BTC) in aqueous solutions was studied in wide ranges of pH and actinyl ion concentrations. The compositions of the forming hexavalent actinide complexes were determined. Their apparent stability constants beta(1)' depend on pH of the solution: in the pH range 2-4, log beta(1)' from 2 to 4 for the complexes of U(VI), Np(VI), and Pu(VI) with 1,2,3-BTC and from 1.5 to 3.5 for the complexes with 1,2,4-BTC. For Np(V), the beta(1)' values are close with both acids, and at equal pH values the Np(V) complexes are less stable than the An(VI) complexes (An = U, Np, Pu). With an increase in pH from similar to 3 to 6.2-6.9, log beta(1)' of the Np(V) complexes increases approximately from 0.5 to 3. Solid U(VI) complexes with 1,2,3- and 1,2,4-benzenetricarboxylic acids were synthesized by the hydrothermal method, their crystal structure was determined, and the IR spectra were examined.

Electron and IR spectra of the compounds as well as the results of thermal analysis correlate with their structure. An actinide contraction effect is demonstrated by a decrease in the An–O interatomic distances and the volumes of An atom coordination polyhedra and Voronoi–Dirichlet polyhedra.

  Neptunium(VI) and plutonium(VI) monophthalates were prepared and characterized. The complexes AnO2 (COO)2C6H4 ⋅ 2H2O were isolated from cold solutions, and AnO2 (COO)2C6H4 ⋅ 1.33H2O, from hot solutions. NpO2 (COO)2C6H4 b. 2H2O and PuO2 (COO)2C6H4 ⋅ 2H2O crystalize in the triclinic and monoclinic systems, respectively. The complexes AnO2(COO)2C6H4 ⋅ 1.33H2O are isostructural and crystallize in the rhombohedral system. The thermal behavior of these complexes was studied. Their IR and electronic absorption spectra were recorded. The properties of these complexes were compared to those of known U(VI) monophthalates.
