Brazilian Journal of Thermal Analysis, Araraquara, v. 2, n. 1, p. 1-5, Dec. 2013.http://repositorio.bc.ufg.br/handle/ri/15387Solid state M(2-MeO-BP)2 compounds, where M stands for bivalent alkali earth metal ions (Mg, Ca, Sr and Ba) and 2-MeO-BP is 2-methoxybenzylidenepyruvate, have been synthesized. Simultaneous thermogravimetry and differential thermal analysis (TG-DTA), differential scanning calorimetry (DSC), infrared spectroscopy, elemental analysis and complexometry, were used to investigate these compounds. The dehydration of magnesium, strontium and barium compounds occurs in a single step, while for calcium compound the dehydration occurs in two steps. The thermal decomposition of the anhydrous compounds occurs with the formation of carbonate as intermediate, except for the magnesium compound. The results also provided information about the composition, coordination mode, thermal behavior and thermal decomposition of isolated compounds.engAcesso AbertoAlkali earth metalsMethoxybenzylidenepyruvateThermal behaviorArtigo10.18362/bjta.
