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)·H_2O]_n(1),{[Co(L)·H_2O]_2·5H_2O}_n(2)(H_2L=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。
Two transition metal coordination polymers [Cu (L) · H_2O] _n (1) were synthesized under hydrothermal conditions using 5- (pyridin-2-ylmethoxy) (H 2L = 5- (pyridin-2-methoxy) -isophthalic acid) was synthesized and characterized by X-ray single crystal diffraction, infrared spectrum , X-ray powder diffraction, elemental analysis and thermogravimetric analysis. Structural analysis shows that complex 1 is a two-dimensional planar structure of the monoclinic P21 / n space group and presents a 2-node (3,4) -connected topological network. 2 is a one-dimensional chain structure of triclinic and P1 space group, and a three-dimensional supramolecular network structure is constructed under the action of intermolecular hydrogen bonds. At the same time, the luminescent properties of complexes 1 and 2 were studied.
