Resumo

METHOD FOR OBTAINING [Zn(BDC)(H 2 O) 2 ] n METAL-ORGANIC FRAMEWORK.This work presents the optimization of the microwave-assisted hydrothermal synthesis of [Zn(BDC)(H 2 O) 2 ] n .The reactions were carried out at the fixed temperature of 120 ºC for 10, 20, 30 and 40 min.Pure crystalline [Zn(BDC)(H 2 O) 2 ] n was obtained in high yield (ca. 90%) with a reaction time of 10 min.The phase obtained and its purity was confirmed by Rietveld refinement, with a final value for R wp /R exp equal to 1.48.Increased reaction times (20, 30 and 40 min) favored the formation of unwanted by products, resulting in mixtures of several crystalline phases.
