摘要: 利用UV、MCD、Raman、EPR、Mssbauer、循环伏安等手段,研究了新型尾式卟啉铁-氯化中位一[邻-(4-二甲胺基丁酰胺基)苯基]三苯基卟啉合铁配合物不同价态下的轴向配位状态和它与含N碱及小分子CO、NO的轴向加合性质。结果表明:尾式卟啉铁(Ⅲ)呈现五配位高自旋(S=5/2)状态:尾端叔胺N不能与中心离子铁(Ⅲ)配位,而可以与铁(Ⅱ)生成五配位低自旋配合物。

关键词: 尾式卟啉铁, 轴向配体

Abstract: Atailed porphyrin iron complex, meso-mono-CO-(4-dimethylamino butylami-do) phenyl] triphenylporphyrin iron (Ⅲ) chloride has been prepared. Experimental results by EPR, UV,Raman, Mossbauer, MCDand cyclic voltammetry methods demonstrated that high-spin iron (Ⅲ)complex shows no intermolecular coordination of the terminal group on the metal ion while five-coordinate ferrous com-plexes are formed with axial ligands.

Key words: Tailed porphyrin iron, Axial ligand
