Resumo

Solid-state Ln -3-MeO-Bz compounds, where Ln stands for lighter trivalent lanthanides (La –
Sm) and 3-methoxybenzoate, have been synthesized. Thermogravimetry (TG), differential scanning
calorimetry (DSC), X-ray powder diffractometry, infrared spectroscopy, and complexometry were used
to characterize and to study the thermal behaviour of these compounds. The results led to information
concerning the composition, dehydration, polymorphic transformation, thermal behaviour and thermal
decomposition of the synthesized compounds.
