| As the ligand, triazole has been widely attention not only because it's smaller cubage, stronger ability to connect metal centers, but also because of their variety of architectures and topologies.Organic ligand usually function as bridge to connect two centers plays the key role in constructing the coordination polymers. In the work, we got ten coordination polymers using two ligands 4-amino-3,5-bis(3-pyridyl)-1,2,4-triazole (3-pytz) and 4-amino-3,5-b is(4-pyridyl)-1,2,4-triazole (4-pytz) with transition metal cations Cd(Ⅱ), Cu(Ⅱ): [Cu(bca)(3-pytz)(H2O)](1),[Cu(FA)(3-pytz)(H2O)] (2),[Cu(3-pytz)(H2O)4] (SO4)·H2O (3), [Cu2(3-pytz)2(H2O)7(SO4)](SO4)·7H2O(4),[Cu(3-pytz)(H2O)3(SO4)]·2H2O(5),[Cu(3–pytz) (H2O)(SO4)](6),[Cd(3-pytz)(H2O)4](SO4)·H2O(7),[Cd(3-pytz)(H2O)(SO4)]·2H2O(8),[Cu(4-pytz)(H2O)3(SO4)]·3H2O (9),[Cu(4-pytz)(H2O)(SO4)]·4H2O (10). The ten compounds have been characterized by elemental analysis, IR Spectra, luminescence analyses, thermogravi-metric analyses and X-ray crystallography and their synthesis are also fully described in this thesis.It shows that,the connection number of O atoms in SO42-are different with the change of synthetical condition. Coordination polymers (3) (4) (5) (6), (7) (8) and (9) (10) have different structures constructed by the same materials by changing solvents or temperature.
