Abstract

ABSTRACT Four new dioxouranium(VI) complexes, [UO2(acac-o-phdn)(L)] where L = H2O, py, DMF and Et3N, with the tetradentate dibasic Schiff base (acac-o-phdn), derived from condensation of acetylacetone with o-phenylene diamine have been synthesized. The infrared spectra were obtained and full assignments of all the observed vibrations are proposed on the basis of C2v symmetry for H2O and py complexes and Cs for the other two complexes, respectively. The bond stretching force constant and bond length of the U=O bond for the four complexes were calculated. Differential thermal analysis (DTA) and thermogravimetric (TG) analysis of the complexes were also carried out.
