Synthesis and Characterization of Dioxouranium (VI) Complexes of Schiff Bases (Mixed-Ligads Part 1)

Abstract

New series of mixed-ligands complexes of dioxouranium (VI) with the Schiff bases and H2O, py, DMF, bipy, phen and Et3N have been synthesized. The elemental analyses, IR, 1H-NMR and 13C-NMR spectra, electronic spectra, magnetic susceptibility measurements and thermogravimetric analyses were used in the synthesis of complexes. The general compositions of the complexes are [(L1)(UO2)(OAc)(H2O)].2H2O (1), [(L2)(UO2)(OAc)(py)].H2O (2), [(L3)(UO2)(OAc)(DMF)].2H2O (3), [(L4)(UO2)(OAc)(bipy)].H2O (4), [(L5)(UO2)(OAc)(phen)].H2O (5) and [(L6)(UO2)(OAc)(Et3N)].3H2O (6).
