摘要
水热条件下,合成了1个镉的配位聚合物{[Cd(L)(HBTC)(H2O)]·H2O}n(L=1,2-二(1,2,4-三氮唑-1-亚甲基)苯,H3BTC=1,3,5-均苯三酸)并对其进行了元素分析,红外光谱,热重以及X射线单晶衍射分析。结构分析表明,镉中心为六配位八面体结构,赤道平面上,4个配位O原子分别来自2个HBTC2-二价阴离子和配位水,轴向上的2个配位N原子来自2个不同的L配体。该配合物是1个二维(4,4)网络结构,并进一步被分子间的O-H…O氢键作用构筑成三维超分子结构。同时研究了配合物的荧光性质。
The new coordination polymer named, {[Cd（L）（HBTC）（H2O）].H2O}n （L=1,2-bis（1,2,4-triazol-l-ylmethyl） benzene, H3BTC =1,3,5-benzenetricarboxylic acid） has been synthesized hydrothermally and characterized by elemental analysis, IR spectroscopy, thermogravimetric （TG） analysis and single-crystal X-ray diffraction analysis. The cadmium center is six coordinated with three Ocoo- atoms from two different HBTC2- dianions and one water molecule locate in the equatorial positions, while apical sites are occupied by two N atoms from two distinct L ligands in a distorted octahedral geometry. The structural analysis shows that the complex possesses a two- dimensional 2D （4,4） layer structure, and displays a three-dimensional （3D） supramolecular structure via multiple intermolecular O-H-..O hydrogen bonds. The fluorescence property of the complex also has been studied. CCDC： 917952.
