New dioxouranium(VI) complexes with the dibasic tridentate 7-carboxaldehyde-8-hydroxyquinoline-aroylhydrazone derivatives (1), have synthesized and is bonded to the axial oxygen of the uranyl moiety and is easily substituted by dimethylsulphoxide. The ligands contain intramolecular hydrogen bonds, one of which is from the enolic form of the hydrazone residue. The1H n.m.r. spectra show that the position of the hydrogenbonded proton of the hydrazone moiety is substituent dependent. The F(U−O) (mydn/Å) and the bond length r(U−O) (Å) of the UO bond are calculated from the i.r. data and related to the electronic properties of the substituents.
