摘　　要：The title complexes Ni(HDPC)2·3H2O and Cu(DPC)(H2DPC)·2H2O have been synthesized in aqueous solution by the reaction of pyridine-2,6-dicarboxylic(H2DPC) with NiCl2·6H2O and CuCl2·3H2O,respectively.The enthalpy change of formation of the reaction on the title complexes in liquid-phase have been determined by a microcalorimeter,respectively. Thermodynamic parameters(the activation enthalpy,the activation entropy and the activation free energy),rate constant and kinetics parameters(the apparent activation energy,the pre-exponential constant and the reaction order) of the title reaction have been calculated.The formation of the two complexes were all exothermic reactions in the range of experimental temperature.The higher reaction velocity was obtained at higher temperature.The title complexes Ni （HDPC）2O3H2Oand Cu（DPC）（ H2 DPC）·2H2O have been synthesized in aqueous solution by the reaction of pyridine - 2,6 - dicarboxylic （H2DPC） with NiCl2 -6H2O and CuCl2 ·3H2O, respectively. The enthalpy change of formation of the reaction on the title complexes in liquid - phase have been determined by a microcalorimeter, respectively. Thermodynamic parameters （the activation enthalpy, the activation entropy and the activation free energy）, rate constant and kinetics parameters （the apparent activation energy, the pre -exponential constant and the reaction order） of the title reaction have been calculated. The formation of the two complexes were all exothermic reactions in the range of experimental temperature. The higher reaction velocity was obtained at higher temperature.
