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。
Under hydrothermal conditions, a coordination polymer of cadmium {[Cd (L) (HBTC) (H2O)] · H2O} n (L = 1,2-bis 1-methylene) benzene, H3BTC = 1,3,5-trimellitic acid) were synthesized and characterized by elemental analysis, IR, TG and X-ray single crystal diffraction. The structural analysis shows that the center of cadmium is hexacoordinated octahedron. In the equatorial plane, the four coordination O atoms come from two HBTC2-dianions and coordination water respectively. The two coordination N atoms in the axial direction are from 2 A different L ligand. The complex is a two-dimensional (4,4) network structure and further formed into a three-dimensional supramolecular structure by O-H ... O hydrogen bonding between molecules. The fluorescence properties of the complexes were also studied.
