ABSTRACT
Complexes of ZrO[2+], UO[2+][2] and Th[4+]with 2-Hydroxyna-phthyl-l-azo-Beta-benzoyl ethyl acetats are synthesized and characterized by elemental analysis, ir,[1]H nmr, electronic spectra and TGA measurements. Moreover, the formation constants of the complexes are evaluated by spectroscopic techniques. The bonding of metal ions to the ligand takes place through the naphtholic and enolic OH groups by proton displacement
