| 摘要: 以柔性配体5-(吡啶-2-甲氧基)-间苯二甲酸为主配体在水热条件下合成了2例过渡金属配位聚合物[Cu(L)·H2O]n (1), {[Co(L)·H2O]2·5H2O}n (2)(H2L=5-(吡啶-2-甲氧基)-间苯二甲酸),并通过X射线单晶衍射、红外光谱、X射线粉末衍射、元素分析和热重分析方法对其进行表征。结构分析表明:配合物1为单斜晶系P21/n空间群的二维平面结构,并呈现2-节点(3,4)-连接的拓扑网络。2为三斜晶系,P1空间群的一维链状结构,在分子间氢键的作用下构筑出三维超分子网络结构。同时对配合物1和2进行了发光性质的研究。 |

| Abstract: Two transition metal coordination complexes[Cu(L)·H2O]n (1), {[Co(L)H2O]2·5H2O}n (2) (H2L=5-(pyridin-2-ylmethoxy)-isophthalic acid) were synthesized through hydrothermal method. They were characterized by single-crystal, IR, PXRD, elemental and TGA analyses. Structural analysis indicated that the complexes 1 and 2 were linked into infinite structures bridged by organic acid ligands. 1 crystallizes in the monoclinic system with P21/n space group and features a 2D layered structure, which possesses a 2-nodal (3,4)-connected topology; 2 crystallizes in triclinic system P1 space group with a 1D structure and further are connected to 3D supramolecular structure via hydrogen bonds. Moreover, compounds 1~2 exhibited photoluminescence in the solid state at room temperature. |
