Notizen:
From solutions of Th(NO3)4 and K2X (X = malonate, succinate and adipate) taken in different molar ratios, the following compounds were isolated: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{l} {\rm Th}({\rm C}_3 {\rm H}_2 {\rm O}_4)_2 \cdot 2{\rm H}_2 {\rm O},{\rm K}_2 {\rm Th}({\rm C}_3 {\rm H}_2 {\rm O}_4)_3, \\ {\rm Th}({\rm C}_4 {\rm H}_4 {\rm O}_4)_2 {\rm \,\,and \,\,Th}({\rm C}_2 {\rm H}_8 {\rm O}_2). \\ \end{array} $$\end{document}Conductometric and heterometric titrations carried out in the systems Th(NO3)4—K2X—H2O besides confirming the existence of the above compounds indicate the presence of yet another specie (ThX)++ in all these systems. Attempts at isolation of this last specie kowever, failed because of the ease with which it was decomposed into ThX2. The system Th(NO3)4—K2C2O4—H2O has also been studied for the sake of the completeness of the investigation.
