ResumoAbstract Reactions of arylazobenzaldoximes, X-(C6H4)C( NOH)N NPh(HL), where X H, p-Cl, p-CH3O, p-NO2, or arylazoformaldoximes, HC( NOH)N N(C6H4Y Y(HL), where Y p-CH3C( O) , p-Cl, p-CH3O, p-CH3, p-NO2, with UO2(OAc)2.·2H2O in methanol yielded complexes with the formula UO2(L)2·ηH2O, where η 1–5. These dioxouranium(VI) complexes were characterized by elemental analyses, conductivity measurements, IR and 1H NMR spectroscopy. In these complexes, the azo-oximes act as bidentate ligands by bonding through the oxime-oxygen and an azo-nitrogen.
