  Syntheses, characterization and luminescent properties of two lead(II) fumarate metal-organic frameworks

  摘要：

  It is of interest that the hydrous 3D metal-organic framework (MOF) {[Pb-2(fum)(2)(H2O)(4)] center dot 2H(2)O}(n) (1) has been synthesized by the reaction of the fum dianion with the lead(II) ion (fum = fumarate) in the presence of pyrazole, while the anhydrous 3D MOF [Pb(fum)](n) (2) is obtained by the reaction of the fum dianion with the lead(H) ion in the presence of pyrazine. These complexes were further characterized by FT-IR spectroscopy. thermogravimetric analysis (TG), X-ray analysis and solid state photoluminescence spectra. The arrangement of the ligands displays a coordination gap around the Pb atom, occupied possibly by a stereoactive lone pair of electrons on lead(II), with the coordination around both the eight-coordinated lead atom in I and six-coordinated lead atom in 2 exhibiting a hemidirected geometry. The fum ligand shows different ligation behavior toward the lead(II) ions in these complexes. These compounds exhibit photoluminescence with the maximum emission located in the UV region.
