摘　　要：The molar dissolution enthalpy of the reactants and the products of the coordination reaction of erbium nitrate with alanine hava been measured by classical solution calorimetry,the calorimetric solvent is 2mol· L－ 1 HCl solution.The standard molar reaction enthalpy of this coordination has been determined by a new chemical circle ,and =17.800kJ· mol－ 1.From the results and other auxiliary quantities ,the standard molar enthalpy of formation of the new complex Er(Ala)4(NO3)3· H2O has been calculated to be [Er(Ala)4(NO3)3· H2O,s, 298.2K]= － 3818.2kJ· mol－ 1.The molar dissolution enthalpy of the reactants and the products of the coordination reaction of erbium nitrate with alanine hava been measured by classical solution calorimetry,the calorimetric solvent is 2mol· L－ 1 HCl solution.The standard molar reaction enthalpy of this coordination has been determined by a new chemical circle ,and =17.800kJ· mol－ 1.From the results and other auxiliary quantities ,the standard molar enthalpy of formation of the new complex Er(Ala)4(NO3)3· H2O has been calculated to be [Er(Ala)4(NO3)3· H2O,s, 298.2K]= － 3818.2kJ· mol－ 1.
