  Sonochemical syntheses of nano lead(II) iodide triazole carboxylate coordination polymer: Precursor for facile fabrication of lead(II) oxide/iodide nano-structures

  摘要：

  Nanoparticles of a one-dimensional coordination polymer [Pb(L)(mu(2)-I)](n) (1), (L = 1H-1,2,4-triazole3- carboxylate), have been synthesized by a sonochemical process and characterized by field emission scanning electron microscopy (FESEM), X-ray powder diffraction (XRPD), FT-IR spectroscopy and elemental analyses. The thermal stability of compound 1 both its bulk and nano-size has been studied by thermal gravimetric (TG) and compared each other. Concentration of initial reagents effects and the role of power ultrasound irradiation on size and morphology of nano-structured compound 1 have been studied and show that low concentrations of initial reagents and also high power of ultrasound irradiation decreased particles size and leaded to uniform nanoparticles morphology. PbO nano-structures were simply synthesized by solid-state transformation of compound 1 at 630 degrees C under air atmosphere whereas thermal decomposition of compound 1 in oleic acid as surfactant at 200 degrees C yield PbI2 nanoparticles.

  Irreversible crystal-to-crystal transformations of 3D lead(II) coordination polymers with the ligand 1H-1,2,4-triazole-3-carboxylic acid (HL), [Pb(L)(mu(2)-Br)(H2O)](n) (1), [Pb(L)(mu(1,1)-NCS)(H2O)](n) (2) and [Pb(L)(mu(2)-Cl)(H2O)](n) (3) to 3D supramolecular compound [Pb(L)(mu(2)-I)](n) (4) by solid state anion-replacement processes under mechanochemical reactions, have been studied. The thermal stabilities of compounds 1-4 were studied by thermogravimetric and differential thermal analyses. The irreversible solid state structural transformations of compounds 1-4, by anion-replacement processes under mechanochemical reaction, have been verified by PXRD measurements. Nanoparticles of compounds 1 and 2 were synthesized by sonochemical process and characterized by scanning electron microscopy (SEM), powder X-ray diffraction, IR spectroscopy, elemental analyses, thermogravimetric and differential thermal analyses. The SEM images showed that no morphology change occurs during solid state anion-replacements of nanocrystals. (C) 2013 Elsevier B.V. All rights reserved.
