Dioxouranium complexes with pentadentate s-triazine Schiff base ligands: Synthesis, crystal structure and optical properties
Original language description
Using the reactions of 2,4-dihydrazino-(R)-s-triazine (R - methoxy (DHMT)) with salicylaldehyde and o-vanillin ligands 2,4-Bis(2-hydroxybenzylidenehydrazino)-6-methoxy-s-triazin (L1) and 2,4-Bis(2-hydroxy-3-methoxybenzylidenehydrazino)-6-methoxy-s-triazin (L2) were obtained. Using the reaction of 2,4-dihydrazino-(R)-s-triazine (R - amino (DHAT)) with o-vanillin ligand 2,4-Bis(2-hydroxy-3-methoxybenzylidenehydrazino)-6-amino-s-triazine (L3) was obtained. By the reactions of the prepared ligands, derivatives of hydrazo-s -triazine, with uranyl acetate or nitrate, three new complexes were prepared. X-ray diffraction shows that the View the MathML source ion is in a pentagonal bipyramidal coordination environment. Two oxygen atoms of the View the MathML source ion occupy the axial positions and three atoms of nitrogen and two atoms of oxygen construct the equatorial plane. The uranyl(VI) complexes were characterized by single-crystal X-ray diffraction, UV-vis, fluorescence and IR spectroscopy. Thermal stabilities of the complexes were investigated using thermogravimetric analysis.
