The ligand 2,6-diformyl-4-methylphenol, H(MDA), transforms slowly into 2-dimethylacetal-4-methyl-6-formylphenol, H(MAC), in warm anhydrous methanol. Both ligands react with uranyl acetate to give the adducts (UO/sub 2/(MDA)/sub 2/(L)) (L=MeOH and EtOH) and (UO/sub 2/(MAC)/sub 2/(MeOH)), whose thermal degradation yields (UO/sub 2/(MDA)/sub 2/) as an intermediate. The condensation reaction of (UO/sub 2/(MAC)/sub 2/(MeOH)) with (H/sub 2/N-CH/sub 2/-CH/sub 2/)/sub 2/S yields the complex ((CH/sub 3/O)/sub 2/CH-OC/sub 6/H/sub 2/CH/sub 3/-HC=N(CH/sub 2/)/sub 2/)/sub 2/SUO/sub 2/, (UO/sub 2/(SMAC)), in which the ligand acts as pentadentate. Ligands and complexes have been characterized by infrared, /sup 1/H and /sup 13/C NMR spectroscopy and by thermogravimetric measurements. Their behavior in MeOH and EtOH solutions is discussed.
