摘　　要：通过选用两种不同的“Y”型含氮配体5-((4-羧基苄基)氨基)间苯二甲酸(H_(3)cpmd)和1,3,5-苯基-均三咪唑(tib)在溶剂热的条件下与金属钴的硝酸盐充分反应,成功制备出一种新型钴配位聚合物材料[Co(Hcpmd)(tib)]_(n)(1)。晶体解析数据显示,钴配位聚合物隶属于单斜晶系,P 2_(1)/c空间群,中心离子Co(II)通过与三个不同的tib配体上的三个N原子和两个不同Hcpmd^(2-)配体上的三个O原子配位相连,形成了一个稍微扭曲的八面体构型。Co(II)离子通过与Hcpmd 2-配体相连形成了一个1D链状结构,而Co(II)离子通过与tib配体相连形成了一个2D平面结构。相邻的两个2D平面结构通过分子之间的氢键作用相连,使得配位聚合物1的呈现3D框架结构。应用研究结果表明,钴配位聚合物可以很好的吸附水溶液中的刚果红染料,是一种潜在的刚果红吸附剂材料。A novel coordination polymer build by 5-((4-carboxybenzyl)amino)isophthalic acid(H_(3) cpmd)and 1,3,5-tris(1-imidazolyl)benzene(tib),namely:[Co(Hcpmd)(tib)]_(n)(1)was synthesized under solvothermal condition.Crystal resolution data showed that the cobalt coordination polymer belonged to the monoclinic crystal system,P 2_(1)/c space group.The central ion Co(II)formed a slightly distorted octahedral configuration by coordination to three N atoms from three different tib ligands and three O atoms from two different Hcpmd ^(2-)ligands.The Co(II)ion formed a 1D chain structure by association with the Hcpmd ligand,and the Co(II)ion formed a 2D planar structure.The two neighbouring 2D planar structures were connected by hydrogen bonding interactions between the molecules,resulting in the presentation of a 3D framework structure for the coordination polymer 1.The results of the applied research showed that cobalt coordination polymers can adsorb Congo red dye in aqueous solution well and was a potential Congo red adsorbent material.
