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,Pī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。
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, IR spectra, 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 2D bilayer structure. Magnetic susceptibility measurement of complex 1 indicates the presence of weak antiferromagnetic interactions between the neighboring Mn(ll) ions. CCDC: 928642.
