Synthesis and Studies of Some New Dioxouranium (VI) Complexes with Azoester Ligands

Some new complexes of uranyl (VI) metal ion with different anions (viz. Cl-,I-,NO-3 and OAc ) have been synthesized using azoester ligand. Complexes were characterized by traditional methods viz. melting point measurements, conductivity measurements. These were also characterized by modern spectral methods viz. IR including far IR, UV –vis. spectra. Thermal studies specially DTA studies of representative have also been done and reported. Some of the complexes were also screened against selected microbes to check their antimicrobial activities. Coordination number of these complexes are proposed to be 8, 10 and 12 and tentative structures of the complexes are also reported in the present paper.
