Octacoordinated dioxouranium(VI) complexes of the tetradentate ONNO donors diacetyl bis(benzoylhydrazone) (H2L) and benzil(benzoylhydrazone) (H2L') are reported.At low pH (1.5-2.5) complexes of the formula (X(-) = Cl(-), Br(-), NO3(-), NCS(-), ClO4(-), OAc(-) or 0.5SO4(2-)) containing the keto form of the ligands are isolated.At higher pH (6-7), the complexes are obtained in which the ligand is present in its deprotonated enolate form (L(2-) or L'(2-)).Reactions of / with neutral monodentate (B) and bidentate lewis bases (AA) lead to the formation of mixed-ligand complexes of the type and respectively.Results of elemental analyses, magnetic susceptibility and conductivity measurements, spectroscopic (IR, electronic etc.) and thermal decomposition studied have been utilised to characterise the complexes.
