Mechanochemical synthesis and characterization of hydrated and dehydrated crystalline strontium terephtalates

Abstract

A successful mechanochemical synthesis of strontium terephthalate trihydrate is described for the first time. The dehydration of Sr(C 8H4O4)-3H2O occurs at about 100 °C and results in a well-defined strontium terephtalate, Sr(C 8H4O4), thermally stable up to 550 °C. Both compounds are not described so far in the literature. Their structures were solved by ab initio structure determination and subsequent Rietveld refinement of the powder diffraction data. Further methods like DTA-TG, MAS NMR and FT-IR spectroscopy, and BET measurements were used to characterize these compounds. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
