Nano-structure of a new 2D double-chain lead(II) coordination polymer, [Pb2(μ-N3)(μ-NO3)L2]n (1), HL = 8-hydroxyquinolin ligand was synthesized by a sonochemical method. The new nano-structure was characterized by scanning electron microscopy, X-ray powder diffraction, IR spectroscopy and elemental analyses. The structure of compound 1 was determined by single-crystal X-ray diffraction and consists of 2D double-chain polymeric units. The coordination number in compound 1 is five and each lead atom is coordinated by one oxygen atom of NO3- anion, one nitrogen atom of 8-hydroxyquinolin ligand, two oxygen atoms of OH group of ligand and one nitrogen atom of N3- anion. The thermal stability of compound 1 was studied by thermal gravimetric and differential thermal analyses (TGA and DTA). Calcination of the nanocompound 1 at 400 °C under air atmospheres yielded nano-sized particles of PbO that characterized by scanning electron microscopy and X-ray powder diffraction.
