| Abstract: | Two new zinc(II) complexes are prepared by reactions of 2-(2'-Hydroxyphenyl)-2-oxazoline(Hoz) with Zn(acac)2 and ZnCl2, respectively. The complexes are characterized by IR and X-ray crystallography. Complex 1 is dinuclear zinc structure bridged by the oxygen atoms from oz- ligand and acac- ligand as terminal chelating ligands. Complex 2 is tetranuclear zinc structure bridged by both μ2-oxygen from oz- ligand and μ3-methoxide. Complex 1 crystalizes in P21 space group with crystallographic parameters: a=9.384 2 Å(19), b=13.584 0 Å(30), c=11.138 0 Å(20), and β=96.250°(30). Complex 2 crystalizes in P-1 space group with the crystallographic parameters: a=9.551 7 Å(19), b=11.123 4 Å(22), c=11.182 6 Å(22), α=102.820°(30), β=114.988°(30), and γ=100.806°(30). The UV absorption and fluorescence emission spectra are measured in the methanol solution and solid state of complex 1, showing strong luminescence. |
