| 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.
