| 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。 |

| Abstract: The new coordination polymer named, {[Cd(L)(HBTC)(H2O)]·H2O}n (L=1,2-bis(1,2,4-triazol-1-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 Natoms from two distinct Lligands 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. |
