摘　　要：用分光光度法研究了酞菁铁[Fe(III)Pc(COOH)4OH]在碱性水溶液中与咪唑类配体的轴向配位反应热力学.测得了反应[Fe( )Pc(COO-)4·OH]4-+nL=[Fe( )Pc--(COO-)4Ln]3-+OH-的平衡常数K,配位数n,标准摩尔焓变△rH0m.The thermodynamic properties were studied for the axial coordination reaction ^(4^-) + nL = COO^-)_4^(3-) + OH^- of 2,9,16,23-tetracarboxyphthalocynineiron(Ⅲ) with imidazolates in potassium hydroxide solution.The equilibrium constant(K) and coordination number of the reaction were measured by spectrophotometry .The standard molar enthalpy(△rH^(0-)_m) and standard entropy(△rS^(0-)_m) of the reaction were calculated.
