Study on the Thermodynamic Properties for the Axial Coordination Reaction of 2,9,16,23-Tetracarboxyphthalocynineiron(Ⅲ) with Imidazolates
【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。
【Abstract】 The thermodynamic properties for the axial coordination reaction(1) of 2,9,16,23-tetracarboxyphthalocynineiron(Ⅲ) with imidazolates in dimethylsulfoxid(DMSO)[Fe(Ⅲ)Pc(COO-)4·OH-]4-+nL=[Fe(Ⅲ)Pc(COO-)4Ln]3-+OH-(1)were studicd.The equilibrium constant(K) and coordination number of reaction(1) were measured by spectrophotometry.The standard molar enthalpy(ΔrH0m) and standard entropy(ΔrS0m) of the reaction(1) were calculated.
