Resumo: In this work the complexes Ln(β-dik)3L (where Ln= Nd+3 e Er+3, β-dik= 4,4,4-trifluoro-1-phenyl-1,3-butanedione (Btfa) and L= 1,10-Phenanthroline (Phen) or 2,2’-Bipyridyl (Bipy)), were synthesized from the direct reaction of LnCl3 with β-diketone and the ligands. The purpose was to create new lanthanide complexes with perspectives of use in markers. After the syntheses, the complexes were characterized by Solubility Test, Scanning Electron Microscopy (SEM) and the thermal properties of compounds were studied using Thermogravimetry Analisys (TGA), Differential Scanning Calorimetry (DSC) and Determination of Melting/Decomposition Intervals. Based on the verified properties, the solubility test found that the complexes are not soluble in chloroform and water. The microscope images showed an excellent crystallization of the complexes. The complexes are stable up to 120°C, after this temperature they show a peak in the DSC referring to the fusion and the beginning of decomposition. The values of activation energy suggests the following decreasing order of stability: Er(Btfa)3Phen>Nd(Btfa)3Phen>Er(Btfa)3Bipy>Nd(Btfa)3Bipy.

El objetivo fue crear nuevos complejos de lantánidos con perspectivas de uso como marcadores. Después de la síntesis, los complejos se caracterizaron mediante Prueba de Solubilidad, Microscopía Electrónica de Barrido (MEB) y las propiedades térmicas de los compuestos se estudiaron mediante Análisis de Termogravimetría (TGA), Calorimetría Diferencial de Barrido (DSC) y Determinación de Intervalos de Fusión/Descomposición. Con base en las propiedades verificadas, la prueba de solubilidad encontró que los complejos no son solubles en cloroformo y agua. Imágenes microscópicas mostraron una excelente cristalización de los complejos. Los complejos son estables hasta 120°C, después de esta temperatura los complejos muestran una pico en DSC con respecto a la fusión y el inicio descomposición. Los valores de energía de activación sugieren el siguiente orden decreciente de estabilidad: Er(Btfa)3Phen>Nd(Btfa)3Phen>Er(Btfa)3Bipi>Nd(Btfa)3Bipi.Neste trabalho os complexos Ln(β-dic)3L (onde Ln = Nd+3 e Er+3, β-dic = 4,4,4-trifluoro-1-fenil-1,3-butanodiona (Btfa) e L = 1,10-Fenantrolina (Phen) ou 2,2'-Bipiridina (Bipi)), foram sintetizados a partir da reação direta de LnCl3 com a β-dicetona e os ligantes. O objetivo foi criar novos complexos de lantanídeos com perspectivas de uso como marcadores Após as sínteses, os complexos foram caracterizados por Teste de Solubilidade, Microscopia Eletrônica de Varredura (MEV) e as propriedades térmicas dos compostos foram estudadas por Análise de Termogravimetria (TGA), Calorimetria Varredura Diferencial (DSC) e Determinação de Intervalos de Fusão/Decomposição. Com base nas propriedades verificadas, o teste de solubilidade constatou que os complexos não são solúveis em clorofórmio e água. As imagens microscópicas mostraram uma excelente cristalização dos complexos. Os complexos são estáveis ​​até 120°C, após esta temperatura os complexos apresentam um pico no DSC referente à fusão e ao início da decomposição.
