Ultrasonic synthesis of two new zinc(II) bipyridine coordination nano-particles polymers: New precursors for preparation of zinc(II) oxide nano-particles

Nanoparticles of two zinc(II) coordination polymers (CPs), [Zn(μ-4,4′-bipy)Cl2]n (1) and [Zn(μ-4,4′-bipy)Br2]n (2) L = bpy = 4,4′-bipyridine ligand, have been synthesized by use of a sonochemical process and characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRPD), Fourier transform infrared spectroscopy (FTIR) spectroscopy and elemental analyses. The single crystal X-ray data of compounds 1 and 2 imply that the Zn+2 ions are four coordinated. Topological analysis shows that 1D coordination networks of 1 and 2 can be classified as underlying nets of topological types 2C1. Nanoparticles of zinc(II) oxide have been prepared by calcination of two different zinc (II) CPs at 450 °C that were characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and IR spectroscopy.
