摘　　要：The Cu（Ⅱ）complexes of 2-aminopyrimidine were synthesized and characterized by elemental analyses,TG-DTG.The dissolution enthalpies of the[AP（s）+CuCl2·2H2O（s）]and Cu（AP） Cl2（s）in 100.00 mL 2 mol.L-1HCl solution were measured at 298.15 K by classical solution calorimetry.The standard molar reaction enthalpy of the coondination reaction of 2-aminopyrimidine with Cu（Ⅱ）has been determined by a thermochemical cycle(ΔrH<sup>○-m=-1.92±0.27kJ·mol-1).From the result,the standard molar enthalpy of formation ΔfH<sup>○-m[Cu（AP）Cl2,s,298.15K] of Cu（AP）Cl2 has been calculated to be-297.46±1.72kJ·mol-1.The Cu（ Ⅱ ）complexes of 2 -aminopyrimidine were synthesized and characterized by elemental analyses,TG- DTG. The dissolution enthalpies of the[ AP（s） ＋ CuCl2 · 2H2O（s） ] and Cu （AP） Cl2（s） in 100.00 mL 2 mol. L^-1 HCl solution were measured at 298. 15 K by classical solution calorimetry. The standard molar reaction enthalpy of the eoondination reaction of 2 - aminopyrimidine with Cu（ Ⅱ ）has been determined by a thermochemical cycle（ △rHm^О- =-1.92±0. 27kJ · mol^-1 ）. From the result, the standard molar enthalpy of formation △fHm^О-[ Cu （AP） Cl2, s,298. 15 K ] of Cu （AP） Cl2 has been calculated to be -297.46 ± 1.72kJ · mol^-1.
