The dioxouranium complex of eight tetradentate ligands bis(isopropanoylacetone) dl-stilbenediimine(dl-H2PA2S), bis(isopropanoylacetone)meso-stilbenediimine(meso-H2PA2S), bis(acetylacetone) dl-H2HAP2S), bis(o-hydroxyacetophenone phenylethylenediiminedl-stilbenediimine (dl-H2AA2S), bis(o-hydroxyacetophenone) meso-stilbenediimine(meso-H2HAP2S), bis-(o-hydroxyacetophenone)dl-stilbeneiimine (dl-H2HAP2Pen), bis (salicylaldehyde) tetramethylethylenediimine (H2SA2Ten) and bis(salicylal dehyde) phenylpropylenediimine (H2SA2PP) have been prepared. The uranyl complexes of H2SA2Ten and H2SA2PP are precipitated as neutral complexes, but remaining are obtained as dinitro derivatives. The complexes are characterised by IR, H-1-NMR and spectrophotometric techniques.
