Abstract
- Utilizing 3,5-bis(x-pyridyl)-1,2,4-triazole(x-Hpytz, x = 3; x = 4) as multidentate ligands, six novel coordination polymers with Zn(ii) or Cd(ii) metal ions were prepared: [Zn(3-pytz)0.5(OH)0.5Cl]n(1, 1D ladder), {[Zn(3-Hpytz)(H2O)4] [Zn(3-Hpytz)(H2O)3·SO4]SO4·5H2O}n(2·5H2O, 1D chain), [Cd(3-Hpytz)(SO4)]n(3, 3D framework), {[Cd(3-Hyptz)SO4·3H2O]·2H2O}n(4·2H2O, 1D chain), [Zn(4-pytz)Cl]n(5, 3D framework) and [Zn2(4-pytz)(SO4)(OH)]n(6, 3D framework). All compounds were obtained from hydrothermal reactions, with the exception of compound 4which was obtained by solvent diffusion at room temperature. All compounds were characterized by FTIR, elemental analysis and TGA analysis and their structures were determined by X-ray diffraction. All compounds exhibited substantial thermal stability and showed photofluorescent properties that resulted from ligand π–π* transition. [ABSTRACT FROM AUTHOR]
