Özet

Nano-structures of two new lead(II) two-dimensional coordination polymers, [Pb-2(2-pyc)(2)(I)(2)](n) (1) and [Pb-2(2-pyc)(2)(Br)(2)](n) (2), {2-Hpyc = 2-pyridinecarboxilic acid} were synthesized by a sonochemical method that produce the coordination polymers at nano-size. The new nano-structures were characterized by scanning electron microscopy, X-ray powder diffraction, IR spectroscopy and elemental analyses. Compounds 1 and 2 were structurally characterized by single crystal X-ray diffraction and consist of two-dimensional polymeric units. The thermal stability of compounds 1 and 2 were studied by thermal gravimetric and differential thermal analyses. PbO and PbBr(OH) nano-structures were obtained by calcination of the nano-structures of compounds 1 and 2 at 400 degrees C, respectively. (c) 2009 Elsevier B.V. All rights reserved.
