摘要 合成两种含吡咯亚胺铁(Ⅱ)配合物Fe[(2-C4H3N(CH=NR]2(1)和Fe[(2-t-Bu-5-C4H3N(CH=NR]2(2)(R=2-MeOPh),并进行元素分析、红外光谱、核磁共振以及X-射线衍射表征.结构分析表明,这两种配合物都含有两个吡咯亚胺配体,但位阻效应对配位形式的影响明显,其中配合物1中的金属铁离子与4个氮原子以及1个氧原子配位,形成五配位的变形平面锥体构型,而配合物2则是由金属铁离子与4个氮原子配位形成变形的四面体结构. The title complexes Fe[（2-C4H3N（CH=NR]2（1） and Fe[（2-t-Bu-5-C4H3N（CH=NR]2（2）（R = 2-MeOPh） were synthesized and characterized by elemental analysis,IR spectroscopy,and X-ray diffraction.The molecular structure showed that both of the title complexes contains two iminopyrrolyl ligands.The steric effect from ligand influence the binding mode： in complex 1,the Fe（Ⅱ） ion is coordinated by four nitrogen atoms and one oxygen atoms to form a distorted 5-coordinated square pyramidal geometry;in complex 2,the Fe（Ⅱ） ion is coordinated by four nitrogen atoms to form a distorted 4-coordinated tetrahedral geometry.
