摘要
通过溶剂热法合成了 3 个锌的配位聚合物{[Zn2(bipmo)2(ipa)2]·3H2O}n(1)、{[Zn(bipmo)(5-OH-ipa)]·DMA·H2O}n(2)和{[Zn(bipmo)(5-Me-ipa)]·H2O}n(3),其中 bipmo=双(4-(1H-咪唑-1-基)苯基)甲酮,H2ipa=间苯二甲酸,5-OH-ipaH2=5-羟基间苯二甲酸,5-Me-ipaH2=5-甲基间苯二甲酸.用元素分析、红外光谱和单晶X射线衍射等技术对结构进行了表征.单晶X射线衍射分析表明,配合物1具有二重互穿的{44·62}二维网络结构,配合物2则是{65·8}拓扑的二维结构,配合物3却表现为二维的{63}拓扑网络.间苯二甲酸上5-位取代基的不同对最终的结构形成有重要的影响.此外,对化合物1～3的发光性质也进行了详细研究.
Abstract
Three zinc coordination polymers,{[Zn2(bipmo)2(ipa)2]·3H2O}n(1),{[Zn(bipmo)(5-OH-ipa)]DMA·H2O}n(2),and {[Zn(bipmo)(5-Me-ipa)]·H2O}n(3),where bipmo=bis(4-(1H-imidazol-1-yl)phenyl)methanone,H2ipa=isoph-thalic acid,5-OH-ipaH2=5-hydroxyisophthalic acid,5-Me-ipaH2=5-methylisophthalic acid,were synthesized under solvothermal conditions.These complexes have been characterized by elemental analyses,IR spectra,single-crystal X-ray diffraction,etc.Complex 1 shows a 2D 2-fold interpenetrating {44·62} network.Complex 2 displays a 2D uninodal framework with the {65·8} topology.Complex 3 reveals a 2D layer structure with {63} topology.The results indicate that the presence of a 5-substituted group in the isophthalate exerts a significant influence on the formation of the final structures.The luminescent properties of the complexes in the solid state have also been studied.CCDC:2297183,1;2297184,2;2297185,3.
