Sonochemical and the structural characterization of novel the Cd(II) nano metal-organic polymer

In two past decades new classes of molecular materials, known as coordination compounds or metal-organic hybrid materials have attracted remarkable attention due to their interesting properties. The research activities in this area have spread widely and rapidly and their fundamental properties are studied more than before [1]. Such compounds in most cases result from self-assembly. The self-assembly process is led by the interactions between primary structural units and their growth in several dimensions [2]. In the present work, we investigate the coordination behaviors of Cd(II) with pyridin- 2-isonicotinohydrazide (L) Schiff-base ligand. The compound was characterized by scanning electron microscopy (SEM), elemental analysis, IR spectroscopy, X-ray powder diffraction (XPRD), and single crystal X-ray analysis. The X-ray structure analysis revealed that the Cd(II) atom is coordinated by one oxygen and three nitrogen atoms from two L ligands and two oxygen atoms of single nitrite anion witha CdN3O3 donor set with distorted octahedral geometry. We describe a facile sonochemical method for synthesis of a nanostructures of this coordination polymer and its use in the preparation of cadmium(II) oxide nanoparticles. CdO nanoparticles were prepared by thermolysis of compound 1 at 180 °C with oleic acid as a surfactant. The average diameter of the nanoparticles was estimated by XPRD to be 23 nm. The morphology and size of the prepared CdO nanoparticles were further studied using SEM.
