水热条件下,以1,4-双(咪唑基-1-甲基)苯(bix)及方酸阴离子(C4O42-)为配体,合成了新的镉的配位聚合物[Cd(C4O4)(bix)(H2O)2]n(1)。单晶结构分析表明,该配合物为二维层状结构,镉中心为六配位八面体结构,赤道平面上4个配位原子分别来自方酸和bix配体,轴向2个配位原子来自配位水分子,镉原子通过双配体桥连形成四连接的二维(4,4)网络。同时,测定了配合物的热稳定性和荧光性质。
Under hydrothermal conditions, a novel coordination polymer of cadmium [Cd (C4O4) 4] has been synthesized by using 1,4-bis (imidazolyl-1-methyl) benzene and squaric acid anion (C4O42-) ) (bix) (H2O) 2] n (1). Single crystal structure analysis shows that the complex is a two-dimensional layered structure, the center of cadmium is a hexacoordination octahedron structure, the four coordination atoms in the equatorial plane come from the squaric acid and bix ligands respectively, and the axial two coordination atoms From the coordination water molecule, the cadmium atoms bridge through the two ligands to form a four-linked two-dimensional (4,4) network. Meanwhile, the thermal stability and fluorescence properties of the complexes were also determined.
