Abstract
Thermal decomposition processes of several palladium complexes with propylenediaminetetraacetic acid(PDTA-H 4) have been studied using DTA, TG and DTG techniques. Intermediate products in the decomposition processes were characterized by IR spectroscopy. For all the compounds, decarboxylation proceeds in two stages, free carboxylic groups being lost in the first step and coordinated carboxylate groups in the second. For the complexes containing ethylenediamine and thiocyanate, the processes are complicated by the presence of these ligands. PdO has been detected as the final product in the decomposition processes, although in the complex [Pd 2(CNS) 2(PDTA-H 2)]·2 H 2O, PdSO 4 is also formed.
