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)center dot H2O (1), [Cu(3-bpt)(H2O)(4)][Cu(3-bpt)(H2O)(3) (SO4)](SO4)center dot 7H(2)O (2), [Cu(3-bpt)(H2O)(3)(SO4)]center dot 2H(2)O (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.
