Abstract
The novel nano lead(II) 1D zigzag coordination polymer [Pb(p-2-einh)ClO4(MeOH)2]n (1) (p-p-2-einh = (1-(pyridin-2-yl)ethylidene)isonicotinohydrazide) was synthesized by a sonochemical method. The new nanostructure was characterized by using scanning electron microscopy (SEM) and high-resolution transmission electron microscopy, X-ray powder diffraction and elemental analysis. The single-crystal X-ray analysis reveals a one dimensional zigzag coordination polymer structure for 1, that is further extended into a three-dimensional (3-D) supramolecular structure by π–π and other labile intermolecular interactions. The coordination number of the lead(II) ions is six, PbN3O3. The PbO nanoparticles were obtained by the thermolysis of 1 at 180 °C in presence of oleic acid as a surfactant. The Scherrer equation estimated the average diameter of the nanoparticles to be 15 nm. The morphology and size of the prepared PbO samples were further observed using SEM. The structure of the title complex has been optimized by density functional theory calculations. Calculated structural parameters and IR spectra for the title complex are consistent with the crystal structure.
