基于锌离子与柔性双咪唑配体构筑的α-Po网格

The α-Po Network Based on Zn(Ⅱ) Ion and Flexible Bisimidazole

  • 摘要: 以1,4-二(1-咪唑基甲基)苯(L)和Zn(NO32·6H2O为原料,在水热条件下合成了一例新的配位聚合物——Zn(L)3(NO321),通过元素分析、红外光谱、X-射线单晶衍射、X-射线粉末衍射等技术对所得单晶进行结构表征.结果表明:该配合物属于三斜晶系、P-1空间群,呈现三重穿插的三维网格特征.Zn(Ⅱ)作为中心离子可被视为6-连节点,通过中性配体L桥联,形成一个带正电荷的α-Po(pcu)网格,游离的NO3-阴离子位于网格孔道中.另外,还研究了该配合物在室温条件下的荧光和热稳定性.

     

    Abstract: A new compound,Zn(L)3(NO3)2 (1), was synthesized by 1,4-bis(imidazol-1-ylmethyl)benzene (L) and Zn(NO3)2·6H2O under hydrothermal condition. The structure was characterized by elemental analysis, IR spectroscopy,single crystal X-ray diffraction, and powder X-ray diffraction.The results showed that tile compound exhibited a triply interpenetrating three-dimensional (3D) framework with triclinic system, space group P-1. The central ion Zn(Ⅱ) could be regarded as six-connected node, which was bridged by the neutral ligand L to form a α-Po (pcu) network with positive charges. In addition, the photoluminescence property in the solid state and thermal analysis of compound 1 were also investigated.
