| 摘要: 以4,4'-联苯咪唑(4,4'-bibp)和间苯二甲酸(H2MPA)为配体,用水热法合成了1个二维锰(Ⅱ)配位聚合物{[Mn(4,4'-bibp)(MPA)]·4H2O}n(1),对其进行了元素分析、红外光谱、X-射线粉末衍射(PXRD)、热重(TGA)和磁性等表征,并用X-射线单晶衍射法测定了配合物的单晶结构。该配合物属于三斜晶系,Pl空间群,为二维双层结构。配合物1的变温磁化率测试结果表明在相邻的锰(Ⅱ)离子之间存在弱的反铁磁相互作用。 |

| Abstract: A 2D complex {[Mn(4,4'-bibp)(MPA)]·4H2O}n (1), based on mixed-ligands bibp (bibp=4,4'-bisimidazol-ylbiphenyl) and H2MPA (H2MPA=m-phthalic acid), has been synthesized by hydrothermal method and charac-terized by elemental analysis, IRspectra, XRD, TGA, and the crystal structure was determined by single-crystal X-ray diffraction. The complex crystallizes in the triclinic system, space group Pl, and features 2Dbilayer structure. Magnetic susceptibility measurement of complex 1 indicates the presence of weak antiferromagnetic interactions between the neighboring Mn(Ⅱ) ions. CCDC: 928642. |
