中文摘要：
在水和四氢呋喃的混合溶液中快速、方便、高产率地合成了一种间苯二甲酸与吡啶和钴的配位聚合物[Co（ipt）（py）3]n（ipt=1,3-二羧基苯甲酸,py=吡啶）,用元素分析、红外光谱对其进行了表征,单晶X射线衍射测定了配位聚合物的晶体结构.结果表明,此配位聚合物属于单斜晶系,P21/c空间群,晶胞参数a=0.914 2（6）nm,b=1.541 3（10）nm,c=1.821 7（9）nm,β=117.98（2）°,V=2.267（2）nm3,Z=4,F（000）=948.在晶体结构中,Co（Ⅱ）处于变形的四方锥配位几何构型中心,分别与来自两个间苯二甲酸的羧基氧和来自三个吡啶上的氮配位,自组装成一维链状结构.紫外-可见吸收光谱表明,配体与金属离子配位后吸收峰发生红移.另外,电化学性质表明标题配位聚合物的电解过程是准可逆过程.
英文摘要：
The coordination polymer [Co（ipt）（by）3]n（ipt=isophthalate,by=pyridine） is synthesized in H2O-THF mixture solution and characterized by elemental analysis and IR.The moleculars structure is determined by single crystal X-ray diffraction.The results show that the complex crystallizes in the Monoclinic system with space group P21/c,a=0.914 2（6）nm,b=1.541 3（10）nm,c=1.821 7（9）nm,β=117.98（2）°,V=2.267（2）nm3,Z=4,F（000）=948.In crystal,the centric Co（Ⅱ） is in a tetragonal pyramid coordination environment,which is defined by two carboxylic oxygen atoms from two different ipt2-anions,and three coordinated N atom from three pyridine molecules and displays a one-dimensional line topology.The UV-vis shows that the absorbance happened red shift of the complexing that ligands and metal ion.In addition,the results of the electrochemical properties show that the coordination polymer exhibits a quasi-reversible electrode process.
