摘要：
Nano-structures of two new Pb(II) two-dimensional coordination polymers, [Pb(2-pyc)(NCS)](n) (1) and [Pb(3-pyc)(NCS)](n) (2) (Hpyc = pyridinecarboxylic acid) were synthesized by a sonochemical method. 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. The crystal structure of these compounds consists of two-dimensional polymeric units. The thermal stability of compounds 1 and 2 were studied by thermal gravimetric and differential thermal analyses. PbS nano-structures were obtained by calcinations of the nano-structures of compounds 1 and 2 at 400 degrees C. (c) 2008 Elsevier Masson SAS. All rights reserved.
