The molar dissolution enthalpy of the reactants and products were measured by classical solution calorimetry, the calorimetric solvent is 4 mol·L-1HCl,at 298.2 K. Using a thermochemistry cycle, the standard molar formation enthalpy of complex Na2[Zn（Cys）2]·5H2O has been calculated to be △fHmNa2[Zn（Cys）2]·5H2O（s）=-2828.323 kJ·mol-1.The result supplies a basic thermochemistry parameter for the further research of the complex.展开更多
