Abstract: | 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.Translated from Radiokhimiya, Vol. 46, No. 5, 2004, pp. 389–395.Original Russian Text Copyright © 2004 by Krot, Bessonov, Grigorev, Charushnikova, Makarenkov. |
