Thermodynamic Properties of Actinide Complexes. Uranyl(VI)- and Thorium(IV)- Glycine Systems. P. Di Bernardo, A. Cassol, G. Tomat, A. Bismondo, and L. Magon. Thermodynamics of the Complex Formation between Thorium(IV) and some Polydentate Ligands in Aqueous Solution. J. Chem. Soc. Dalton Trans., 733-735 (1983).

Potentiometric and calorimetric investigations of uranyl(VI) and Th(IV) complexes with glycine were carried out in 1.00 M aq. NaClO4 at 25 °C. The treatment of the exptl. data has shown that in the examd. systems the glycine acts as unidentate ligand through the carboxylate group, while the amino group is not involved in coordination. The values obtained for the stability consts. and for the heat and entropy changes are discussed.
