摘要
A 4,4′-bipyridine Zn(II) complex [Zn(4,4′-bipy)2(H2O)4](ClO4)2·4(4,4′-bipy) is synthesized, characterized by elemental analysis, IR, 1H NMR, 13C NMR spectroscopy, and studied by X-ray crystallography. The compound forms monomeric units as a result of unusual unidentate coordination of 4,4′-bipy ligands. The thermal stability of the compound is studied by thermal analyses. Furthermore, the complex is luminescent with emission maxima at 329 nm in the methanol solvent. Different sizes of zinc(II) oxide nanoparticles are prepared by calcination of the [Zn(4,4′-bipy)2(H2O)4](ClO4)2·4(4,4′-bipy) compound at two different temperatures. These nanostructures are characterized by X-ray powder diffraction and scanning electron microscopy.
