摘要:Hydrothermal reactions of 3-cyanopyridine and Na N3 with Zn Cl2 or Cd Cl2·5/2H2 O in the presence of 1,4-benzenedicarboxylic acid(H2bdc) yielded two new coordination polymers,{[Zn(3-ptz)(bdc)0.5(H2O)2]n·2H2O}n(1) and [Cd2(3-ptz)2Cl2]n(2),based on in situ synthesized 5-(3-pyridyl)tetrazolate(3-ptz-) organic ligand.They have been structurally characterized by elemental analysis(EA),infrared spectroscopy(IR) and single-crystal/powder X-ray diffraction(PXRD).In 1,two Zn(Ⅱ) ions are linked together through two μ2-(3-ptz-) ligands to form a dimeric unit of [Zn(μ2-3-ptz)(H2O)2]22+,which is further connected with other equivalent units by μ2-bdc2-spacers,resulting in an infinite 1D polymeric chain of [Zn2(3-ptz)2(H2O)2(bdc)]n,and then strong hydrogen bonding interactions extend these 1D chains into a 3D supramolecular structure.In 2,the Cd(Ⅱ) ions are connected through μ4-(3-ptz-) ligands and Cl-anions,leading to infinite 2D layers of [Cd2(3-ptz)Cl2]nn+,which are further linked by another μ4-(3-ptz-) pillared ligand to form a 3D layered-pillared framework architecture of [Cd)2(3-ptz))2Cl)2])n.Furthermore,thermal stability of these compounds was measured by thermogravimetric analysis(TGA) and their photoluminescent properties were also investigated in the solid state at room temperature.
