Summary:Solid state compounds of 4-methylbenzylidenepyruvate with Al(III), Ga(III), In(III) and Sc(III) have been synthesized. Complexometry, X-ray powder diffractometry, infrared spectroscopy and simultaneous thermogravimetry-differential thermal analysis (TG-DTA) have been used to characterize and to study the thermal behavior of these compounds. The results provided information concerning the stoichiometry, crystallinity, thermal stability and thermal decomposition of these compounds. Os 4-metilbenzalpiruvatos de Al(III), Ga(III), In(III) e SC(III), foram sintetizados no estado sólido. Na caracterização e estudo do comportamento térmico desses compostos foram utilizados a complexometria, difratometria de raios X pelo método do pó, espectroscopia na região do infravermelho e termorgravimetria-análise térmica diferencial simultâneas (TG-DTA). Os resultados forneceram informações com respeito a estequiometria, cristalinidade, estabilidade e decomposição térmica desses compostos.
