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
