The equilibrium constants of picket frnce porphyrin iron(Ⅱ) and Cobalt(Ⅱ) complexes with some nitrogenous ligands were determined by UV spectrophotometry. The vc-o of their car-bonyl complexes were determined by IR spectrophotometry. The euqilibrium constants of porphyrin iron (Ⅱ) with nitrogenous ligands are related to the basicity and steric hindrance of ligands. The equilibrium constants of porphyrin iron(Ⅱ ) with ligands are greater much than porphyrin cobalt(Ⅱ)' s.

以可见一紫外分光光度法测定“栅栏”型卟啉铁(Ⅱ)、钴(Ⅲ)与某些含氮配体作用的平衡常进,以红外光谱法测定它们的羰基配合物的C—O振动频率。结果表明:卟啉铁(Ⅱ)与含氮配体的平衡常数既与配体的碱性有关,也与配体的空间位阻有关;卟啉铁(Ⅱ)与配体的平衡常数大于卟啉钴(Ⅲ)。

Coordination properties between two new tailed porphyrin iron (Ⅲ) complexes, 5-[o-(4-(1-imidazolyl)butoxyl)phenyl]-10,15, 20-triphenylporphyrinatoiron (Ⅲ) chloride {[FeⅢ(ImTPP)]Cl} and 5-[p-(4-(3-pyridyloxyl)butoxyl]phenyl-10, 15, 20-triphenylporphyrinatoiron (Ⅲ) chloride {[FeⅢ (PyTPP)]Cl}, with nitrogenous ligands and the equilibrium constants for the addition of these ligands to [FeⅢP]Cl in chloroform were studied by spectral technique. Experimental results demonstrated that [FeⅢ(PyTPP)]Cl, just similar to [FeⅢ(TPP)]C1, form 1:2 adducts with imidazole or pyridines, respectively, but [ FeⅢ(ImTPP)] Cl forms only 1:1 adducts with pyridines and form 1:2 adduct with imidazole. The equilibrium constants for the addition of nitrogenous ligands to [FeⅢ(ImTPP)]Cl are 10- 103 times as big as those for [FeⅢ(TPP)]Cl system. We believe that this result is from the fact that the axial coordination of these ligands to [ FeⅢ(ImTPP)] Cl induces the coordination of terminal imidazole group with ferric iron in [FeⅢ(ImTPP)]Cl and this kind of coordination mode strengthens the bonding between ferric ion in [FeⅢ(ImTPP)]Cl and nitrogen atom in ligand. The novel coordination mode and its structure were identified by the experimental data from UV-vis, 1H NMR and low-temperature EPR.

用分光光度法研究了咪唑或吡啶类配体与5-[邻-(4-(1-咪唑基)丁氧基)苯基]-10,15,20-三苯基卟唑合铁(Ⅲ)氯化物[[Fe~Ⅲ(ImTPP)]Cl]和5-[对-(4-(3-吡啶氧基)丁氧基)苯基]-10,15,20-三苯基卟啉合铁(Ⅲ)氯化物[[Fe~Ⅲ(PyTPP)]Cl]两种尾式铁(Ⅲ)卟啉的轴向加合作用,测定了平衡常数、热力学参数及含氮配体的加合分子数.结果表明,[Fe~Ⅲ(PyTPP)Cl与[Fe~Ⅲ(TPP)]Cl相类似,均与咪唑、吡啶类配体生成1:2低自旋六配位加合物.含氮配体与[Fe~Ⅲ(ImTPP)]Cl的轴向加合反应平衡常数比与[Fe~Ⅲ(TPP)]Cl相应的平衡常数大10~10~3倍,这是因为含氮配体与[Fe~Ⅲ(ImTPP)]Cl的轴向配位诱导了尾端咪唑基与配合物中的Fe~Ⅲ离子的轴向配位,这种配位模式增强了含氮配体与Fe~Ⅲ离子的键合;尾端咪唑基与配合物中的Fe~Ⅲ离子配位的模式得到了UV—vis、~1H NMR及EPR实验数据的进一步证实.
