Sonochemical Synthesis of Nano-structured Lead(II) Coordination Polymer with 2-Aminonicotinic Acid: Thermal, Structural and X-ray Powder Diffraction Studies

A new one-dimensional crystalline and nano-structured Pb(II) coordination polymer, [Pb(2-anc)(2)(NO3)(2)] (n) (1) {2-Hanc = 2-aminonicotinic acid}, were synthesized via heat gradient and sonochemical methods. The new produced nano-structure was characterized by scanning electron microscopy, X-ray powder diffraction, IR spectroscopy, and elemental analyses. Structural characterization by single crystal X-ray diffraction exhibits two-dimensional polymeric units for compound 1. Thermal stability of nano and bulk samples of compound 1 were studied and compared. PbO nano-particles was then obtained via calcination of nano-compound 1 at high and low temperatures. The calcinations result demonstrates that compound 1 may be suitable precursor for the preparation of nanoscale lead(II) oxide without need for special conditions like high temperature, long times and pressure control.
