Abstract: | A novel mixed-ligand zinc(II) coordination polymer, {[Zn(μ-4,4'-bipy)(μ-3-bpdh)(H(2)O)(2)](ClO(4))(2)·(4,4'-bipy)(0.5)}(n) (1); 3-bpdh=2,5-bis(3-pyridyl)-3,4-diaza-2,4-hexadiene and 4,4'-bipy=4,4'-bipyridine, has been synthesized and characterized by IR, (1)HNMR and (13)CNMR spectroscopy. The single crystal X-ray data of compound 1 shows that this coordination polymer grows in two dimensions by two different bridging ligands, 4,4'-bipy and 3-bpdh. Also, nano-scale of compound 1 has been synthesized by sonochemical method and characterized by IR, X-ray diffraction (XRD) and scanning electron microscopy (SEM). Thermal stability of compound 1 in single crystalline and nano-scale form was carried out by thermal gravimetric (TG) and differential thermal analysis (DTA). The ZnO nanoparticles were obtained by calcination of compound 1 at 500°C under air atmosphere and by thermolyses in oleic acid at 200°C. The zinc(II) oxide nanoparticles were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). |
