Description
Summary:This work presents an study related to the synthesis and structural analysis of manganese complex with ligands of bases Schiff type, derivate from pyridoxine. Was used like starting material for the synthesis of ligands pyridoxine chlorhydrate and primary amines, with aromatic chain, in addiction the chloride, perchlorate and manganese acetate, for these complex synthesis. The synthesized compounds was: [Mn(pyr2etileno).2H2O]Cl (1), [Mn (pyr2etileno).H2O.MeOH]Cl (2), [Mn (pyr2pen).2H2O]ClO4 (3), [Mn2(pyr6but3)] (4), [Mn(pyr2aminoprop).H2O]ClO4 (5), [Mn(pyr2amimopropet)]ClO4 (6) and [Mn(pyr2piper)]ClO4 (7). Was made na strucural study of these compounds in solid state, was use X-ray diffraction in monocristal. For the superoxide dismutase (SOD) activity test of this complex was used these methods: ultraviolet and cyclic voltammetry. In addiction of, all the compounds was characterized through elemental analyses and infrared spectroscopy. === Este trabalho apresenta o estudo relacionado à síntese e a analise estrutural de complexos de manganês com ligantes do tipo bases de Schiff, derivados do piridoxal. Utilizaram-se como reagentes de partida para síntese dos ligantes cloridrato de piridoxal e aminas primárias, com cadeias alifáticas, além de cloreto, perclorato e acetato de manganês, para síntese dos complexos. Os compostos sintetizados foram: [Mn(pyr2etileno).2H2O]Cl (1), [Mn (pyr2etileno).H2O.MeOH]Cl (2), [Mn (pyr2pen).2H2O]ClO4 (3), [Mn2(pyr6but3)] (4), [Mn(pyr2aminoprop).H2O]ClO4 (5), [Mn(pyr2amimopropet)]ClO4 (6) e [Mn(pyr2piper)]ClO4 (7). Foi realizado um estudo estrutural desses compostos no estado solido, utilizando a difração de raios X em monocristal. Para os testes de atividade superóxido dismutase (SOD) dos complexos foram utilizados os seguintes métodos de Ultravioleta e voltametria cíclica. Além disso, todos os compostos foram caracterizados por analise elementar e espectroscopia no infravermelho.
