| Abstract: | The reaction of 4-amino-3,5-bis(3-pyridyl)-1,2,4-triazole (3-bpt) with copper sulfate in EtOH/H2O solvent yields four coordination polymers Cu(3-bpt)(H2O)4](SO4)·H2O (1), Cu(3-bpt)(H2O)4]Cu(3-bpt)(H2O)3(SO4)](SO4)·7H2O (2), Cu(3-bpt)(H2O)3(SO4)]·2H2O (3) and Cu(3-bpt)(H2O)(SO4)] (4), showing one-dimensional undulated chain, zigzag chain and two-dimensional network. The formations of compounds 1, 2 and 3 are controlled by the EtOH/H2O ratio. The synthesis of compound 4 may be controlled by the EtOH/H2O ratio and the temperature because it is prepared under solvothermal condition. The thermal properties have been investigated. |
