Synthesis, characterization and thermal behavior of solid state compounds of heavy trivalent lanthanide succinates
چکیده انگلیسی

Solid-state Ln–L compounds, where Ln stands for heavy trivalent lanthanides or yttrium(III) (Tb–Lu, Y) and L is succinate, have been synthesized. Simultaneous thermogravimetry and differential thermal analysis (TG-DTA), differential scanning calorimetry (DSC), infrared spectroscopy, TG-DTA coupled to FTIR, elemental analysis, X-ray powder diffractometry and complexometry were used to characterize and study the thermal behavior of these compounds.For the terbium to thulium and yttrium compounds, the dehydration, as well the thermal decomposition of the anhydrous compound occurs in two consecutive steps, while ytterbium and lutetium the dehydration occurs in a single step. The results also led to information about the ligand's denticity, thermal stability and thermal decomposition of these compounds.


► Thermal stability of compounds was investigated.
► Determination of the gaseous products released.
► The results also provided information concerning the denticity of the ligand.
