摘　　要：The title complexes [Dy（p-NBA）3Phen]2-3H2O（Ⅰ） and [Dy（m-NBA）3Phen]2·4H2O（Ⅱ） were synthesized, in the two molecular formulas of which NBA is nitrobenzoate and Phen is 1,10-phenanthroline. The characterizations of the complexes were carried out by means of elemental analysis, UV, IR, XRD and molar conductivity. The thermal decomposition of the two complexes were studied under the non-isothermal condition by DSC, TG-DTG and IR methods in detail. The kinetic parameters of the dehydration process were also obtained by the analysis of DSC curves of the two complexes with Popescu and Vyazovkin methods, respectively.The title complexes [Dy（p-NBA）3Phen]2-3H2O（Ⅰ） and [Dy（m-NBA）3Phen]2·4H2O（Ⅱ） were synthesized, in the two molecular formulas of which NBA is nitrobenzoate and Phen is 1,10-phenanthroline.
