摘 要: 用分光光度法研究了酞菁铁[Fe(Ⅲ)Pc(COOH4)OH]在二甲基亚砜(DMSO)中与咪唑类配体的轴向配位反应热力学。测得了反应(1)的平衡常数K,配位数n,标准摩尔焓变ΔrH0m和标准摩尔熵变ΔrS0m。 The thermodynamic propertiees for the axial coordination rection(1) of 2,9,16,23-tetracarboxyphthalocynineiron(Ⅲ) with imidazolates in dimethylsulfoxid(DMSO) [Fe(Ⅲ)Pc(COO^-)4·OH^-]^4-+nL=[Fe(Ⅲ)Pc(CCO^-)4Ln]^3-+OH^- (1)were studied.The equilibrium constant (K) and coordination number of reaction (1) were measured by spectrophotometry.The standard molar enthalpy (ΔrHn^0) and standard entropy (ΔrSn^0) of the reaction(1) were calulated.
