Abstract: Several new dioxouranium(VI) complexes of Schiff bases [LH2], derived from salicylaldehyde, substituted salicylaldehydes, 2-hydroxy-1-naphthaldehyde and 2-aminothiophenol, have been prepared and characterized on the basis of their elemental analyses, IR and electronic absorption spectra and magnetic susceptibility measurements. The results suggest that each Schiff base is a bivalent anion with tridentate ONS donors from the phenolic oxygen, azomethine nitrogen and thiophenolic sulfur. The formulae were found to be [UO2L]2 for the 1:1 non-electrolytic complexes and a six-coordinate dimeric structure has been proposed for the complexes.
