摘　　要：The thermodynamic properties were studied for the axial coordination reaction（1）of 2,9,16,23-tetracarboxyphthalocynineiron（Ⅲ）with imidazole in dimethylsulfoxide（DMSO）[Fe（Ⅲ）Pc（COOH）4OH]+nL=[Fe（Ⅲ）Pc（COOH）4Ln]++OH （1）The equilibrium constant（K） and coordination number of reaction（1） were measured by spectrophotometry.The standard molar enthalpy(△rH○—m)and standard entropy(△rS○—m)of the reaction（1）were calculated.The thermodynamic properties were studied for the axial coordination reaction （1）of 2,9,16,23 -tetracarboxyphthalo- eynineiron（ Ⅲ ）with imidazole in dimethylsulfoxide（DMSO） [Fe （Ⅲ ）Pc（COOH）4OH] ＋nL= [Fe（Ⅲ ）Pc（COOH）4Ln]^＋ ＋OH- （1） The equilibrium constant（K） and coordination number of reaction （ 1 ） were measured by spectrophotometry. The standard molar enthalpy（ △rHm^φ） and standard entropy（ △rSm^φ ） of the reaction（ 1 ） were calculated.
