摘要： 研究了氯化5-邻[3-(1-咪唑基)丙氧基]苯基-10,15,20-三苯基卟啉合铁(Ⅲ)[o-Im-PrTPPFe(Ⅲ)Cl]与咪唑及吡啶类配体轴向加合物的低温EPR,考察了尾端咪唑基对铁(Ⅲ)自旋态及配位环境的影响.结果表明,o-ImPrTPPFe(Ⅲ)Cl的弱吡啶类配体轮向加合物显示了铁(Ⅲ)离子独特的EPR磁性质,对各加合物的EPR参数进行了晶体场分析,求得了晶体场分裂参数,并据此分析了各加合物中铁(Ⅲ)的配位环境.

Abstract: The low-temperature EPRof axial ligand-adducts of imidazolyl tailed porphyriniron (Ⅲ) complex, 5-o-[3-(1-imidazolyl) propoxyl ] pheny1-1O, l5, 2O-triphenylporphyrlnatoiron (Ⅲ) chloride [o-ImPrTPPFe(Ⅲ)Cl]was investigated.The effect of terminal imidazole group of o-ImPrTPPFe(Ⅲ)Cl on the coordination environment of ferric ion wasprobed.The unique magnet1c properties of the week-basicity pyridlnes-adducts of o-ImPrTPPFe (Ⅲ)Cl were observed at 77 K, and the crystal field EPRanalysis for the adductswas made.

Key words: Tailed porphyrin iron(Ⅲ) complex, Axial ligand-adducts, EPR spectra
