  Synthetic, structural, extraction and theoretical studies of uranyl nitrate dithio-diglycolamide compounds

  摘要：

  Dithio-diglycolamide ligands of the types [(CH2SCH2CONR2)(2)] (where R = (C3H7)-C-1, C4H9, (C4H9)-C-i, C8H17) and [C7H6(SCH2CONR2)(2)] (where R = (C4H9)-C-i) were prepared and characterized. The complex chemistry of these ligands with uranyl nitrate was studied using IR, NMR and ESI-MS techniques and elemental analysis. The structures for two of the compounds, 2 and 4, were determined by the X-ray diffraction method and revealed a bidentate chelating mode of bonding for the ligands in the solid state. The structures further show that the uranyl group is surrounded by six oxygen atoms in a hexagonal bi-pyramidal geometry. Theoretical studies were carried out to explain the relative stability of this chelating mode of ligand bonding. Extraction studies of U(VI), Pu(IV) and Am(III) ions from HNO3 by one of the ligands, namely L-4, in dodecane show appreciable extractions. The extracted metal ions could be back extracted quantitatively using 0.5 M HNO3 or a mixture of 0.5 M HNO3 and 0.5 M H2C2O4. (C) 2014 Elsevier Ltd. All rights reserved.

  compounds were characterized by using IR, 1H NMR spectral techniques and CHN analyses. The structures of compounds 4, 5 and 7 have been determined by using X-ray diffraction methods. The structures show that the ligands bond through the thioether group to the metal centre in all compounds. They show further that the palladium(II) ion is surrounded by four atoms (two halogens and two thio groups in 4 and
