Main Article Content
Abstract
(La – Gd) and L is pyruvate, have been synthesized. Thermogravimetry and derivative thermo-
gravimetry (TG/DTG), differential scanning calorimetry (DSC), X-Ray powder diffractometry,
infrared spectroscopy, elemental analysis, and complexometry were used to characterize and to study
the thermal behaviour of these compounds. The results led to information about the composition, dehy-
dration, ligand denticity, thermal behaviour and thermal decomposition of the isolated compounds.
