Abstract


In our work,two series of Schiff base coordination polymers have been synthesized with hydrothermal method by adjusting the ratio of the reactants, temperature, solvent, pH value and reaction time , which are Co3（salpn）2（CO2）2 （1）、[Ni2Cd（salpn）2（CO2）2（H2O）2]（H2O）2 （2）、Zn2Cd（salpn）2（CO2）2 （3）、Co3（salpn）2（OAc）2 （4）、[Zn2Ni3（salpn）2（dca）2]n （5）、[CdNi2（salpn）2（dca）2]n （6）、[Co2Zn（sapln）2（dca）2]n （7）、[Co2Cd （sapln）2（dca）2]n （8） （salpn = N,N’– bis（salicylidene） -1,3– diamino propane , dca = dicyanamide） , [Zn（C6H5N） （C8H3NO4）·2H2O]n （9） [Cd（C6H5N）（C8H3NO4）·H2O]n （10）和[Co（C6H5N）（C8H3NO4）·2H2O]n. （11）. All the complexes have been characterized by elemental analyses, IR spectra and X-ray diffraction analyses. The thermal analyses shown that the former eight complexes were thermal stabler than the latter three ones.
