Sonochemical synthesis of a novel nanoscale 1D lead(II) [Pb-2(L)(2)(I)(4)](n) coordination Polymer, survey of temperature, reaction time parameters

摘要

One new lead(II) coordination supramolecular complex (CSC) (1D), (Pb-2(L)(2)(I)(4)](n), L = C4H4N2 (1-methyl imidazole), has been synthesized under different experimental conditions. Micrometric crystals (bulk) or nano sized materials have been obtained depending on using the branch tube method or sonochemical irradiation. All materials have been characterized by scanning electron microscopy (SEM), powder X-ray diffraction (PXRD) and FT-IR spectroscopy. Single crystal X-ray analyses on complex 1 showed that Pb2+ ion is 4-coordinated. Topological analysis shows that the complex 1 is 2,3,5C2 net. Finally, the role of reaction time and temperature on the growth and final morphology of the structures obtained by sonochemical irradiation have been studied.
