Syntheses and characterization of two novel germanium dioxide frameworks with occluded ethylenediamine (EDA) and 1,3-propylenediamine (1,3-PDA)

Abstract

Two novel germanium dioxide frameworks with occluded ethylenediamine and 1,3-propylenediamine have been hydrothermally synthesized, denoted as EDA–GeO₂ and 1,3-PDA–GeO₂ and characterized by means of X-ray powder diffraction (XRD), IR spectra and thermal analyses; the chemical compositions of EDA–GeO₂ and 1,3-PDA–GeO₂ are GeO₂ : 0.3 EDA : 0.6 H₂O and GeO₂ : 0.22 (1,3-PDA) : 0.44 H₂O, respectively and the two compounds show similar XRD patterns.
