چکیده مقاله
Metal-organic coordination systems are one of the most important classes of inorganic materials which have been advanced in recent years [1]. Metal-organic coordination systems are a class of organic–inorganic materials consists of metal ions linked together through multi-dentate organic ligands, to form a polymeric chain. These materials have found various applications such as in catalysis, sensing, luminescence, separation and storage used [2]. In this work we investigate the coordination behaviors of Cu(II) with pyridin-2-isonicotinohydrazide (L) Schiff-base ligand [[Cu2(L)2Cl2].(H2O)]n. 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 revealed that the Cu(II) atom is coordinated by one oxygen and three nitrogen atoms from two “L” ligands and one chloride anion with a CuN3OCl donor set with square pyramid geometry. We describe a simple sonochemical synthesis method for a nano structure of this coordination system and its use in the preparation of CuO nano-particles. CuO nanoparticles were obtained by thermolysis of coordination polymer at 180 °C with oleic acid as a surfactant. The average diameter of the nanoparticles was estimated by XPRD to be 38 nm.
