摘　　要：本文采用水热合成方法,选用2,7-二(咪唑-1-基)-9 H-咔唑(L)作为N-质子类有机配体,1,3,5-苯三甲酸(H_(3)BTC)作为羧酸配体,将二者与Cd^(2+)离子配位结合,成功制备了一个镉金属-有机配合物,[Cd(H_(2)O)(L)(HBTC)]·H_(2)O.利用单晶X-射线衍射对配合物的结构进行了表征.通过对配合物的结构分析,可以发现,配合物是一个二维层状结构.其中,HBTC配体通过Cd原子的桥连,形成了一个一维的金属-有机链.N-质子配体L可以看作为连接子,把这些链连接成为配合物的二维层状结构.性质研究表明,配合物除了能够产生的固态荧光性能外,还可以作为Cr_(2)O^(2-)_(7)阴离子的荧光检测试剂,并且具有较高的选择性和抗干扰能力.A cadmium metal-organic complex,[Cd(H_(2)O)(L)(HBTC)]·H_(2)O,was successfully prepared by using 2,7-bis(imidazole-1-yl)-9 H-carbazole(L)as N-donor ligand and 1,3,5-benzenetricarboxylic acid(H_(3)BTC)as carboxylic acid ligand to coordinate with Cd^(2+)ion.The structure was characterized by single crystal X-ray diffraction.The structural analysis indicates that the complex has a two-dimensional layer structure,in which the HBTC ligands are bridged by Cd atoms to form a one-dimensional metal-organic chain.The N-donor ligands L as linkers connect these chains into a two-dimensional layer structure of the complex.Additionally,the complex shows not only a good solid fluorescence property,but also can also be used as a fluorescent detection reagent for Cr_(2)O^(2-)_(7)anion with high selectivity and anti-interference ability.
