摘　　要：基于三种1,10-邻菲罗啉衍生物配体,通过溶剂热合成方法得到了三种双氯桥联双核FeⅡ配合物Fe_(2)(n-L)_(2)Cl_(2)(n-L=n-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)phenol,n=2~4)。配合物1在三斜体系的P-1空间群中结晶,配合物2和3在单斜体系的C2/c空间群中结晶。由于羟基在苯基中的取代位置不同,配合物1-3拥有相似的配体,但存在着不同的氢键网。由于配合物中Fe-Cl-Fe角度的不同,配合物1-3表现出有趣的磁性性质:配合物1和配合物3中两个FeⅡ离子之间存在铁磁耦合,但配合物2中存在反铁磁耦合。Based on three 1,10-phenanthroline derivative ligands,three neutral dinuclear Fe^(Ⅱ) compounds with the general formula Fe_(2)(n-L)_(2)Cl_(2)(n-L=n-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)phenol,n=2-4),were obtained by solvothermal reaction.Compound 1 crystallizes in the space group P1 of triclinic crystal system,and compounds 2 and 3 crystallize in the space group C2/c of monoclinic crystal system.Due to the different position of the OH group in the phenyl,compounds 1-3 possess the similar ligands but different H-bond nets.The magnetic measurements of 1-3 show interesting magnetic properties:ferromagnetic interaction between two Fe^(Ⅱ) ions are found in compounds 1 and 3,but antiferromagnetic coupling in compound 2,which could depend crucially on the Fe-Cl-Fe angle.
