Thorium complexing by malic acid, trihydroxyglutaric acid, tartaric acid, alpha -hydroxyisobutyric acid and mandelic acid was followed by means of ion exchange at various concentrations of complexing agent and pH. The instability constants, and composition of the complexes are listed. The average effective charge on the complex was determined by ion exchange. Polynuclear thorium complexes with hydrogen bridges were formed with malic acid, but not with the rest of the organic complexing agents. A number of thorium complexes were synthesized in acid solution, and analyzed for C,H,H/sub 2/O, and ThO/sub 2/. Structural formulas are presented. The infrared spectra of these compounds show that thorium is bound to the complexing agent by means of the carboxyl group and not by means of the hydroxyl group. The nuclear magnetic resonance experiments indicate the occurrence of polymeric association in thorium acetate. (TTT)
