Synthesis and biological activity of mixed ligand dioxouranium(VI) and thorium(IV) complexes.

Mixed ligand complexes of dioxouranium(VI) and thorium(IV) in the proportion 1:1:1 and 1:2:1 have been synthesized using 8-hydroxyquinoline as a primary ligand and L-proline and 4-hydroxy-L-proline as secondary ligands, respectively. The metal complexes have been characterized on the basis of elemental analysis, molar conductance, magnetic, spectral and thermal studies. The molar conductance studies of the complexes in DMF at 10(-3) M concentrations indicate their non-electrolytic nature.
