采用长三角刚性含n配体三（4-（1h -咪唑基）苯基）胺（tipa）合成了具有“kagom<s:1>双”（kgd）片状结构的镉配位聚合物{[Cd(tipa)2]·2NO3·5DMF}n(1)，并用x射线单晶衍射对其结构进行了表征。Cd（II）离子与来自tipa配体的N原子六配位，形成cdn6八面体几何结构。三叉戟配体将Cd（II）离子连接成二维薄片。在拓扑上，如果将三角形tipa配体和Cd（II）离子分别视为3-连接节点和6-连接节点，则整个二维薄片可以简化为（3,6）连接的kgdnet，其Schläfli符号为（43）2（46·66·83）。此外，还讨论了1在298和77 K下的光致发光和阴离子交换性能。
A cadmium coordination polymer with ‘Kagomé dual’ (kgd) sheet structure, {[Cd(tipa)2]·2NO3·5DMF}n(1), has been synthesized by employing an elongated triangular rigid N-containing ligand tris(4-(1H-imidazol-yl)phenyl)amine (tipa) and structurally characterized by X-ray single-crystal diffraction. The Cd(II) ion is six coordinated with N atoms from tipa ligands, forming a CdN6octahedron geometry. The tridentate tipa ligand connects the Cd(II) ions into a 2D sheet. Topologically, if the triangular tipa ligand and the Cd(II) ions are regarded as 3- and 6-connected nodes respectively, the overall 2D sheet can be simplified to a (3,6)-connectedkgdnet with a Schläfli symbol of (43)2(46·66·83). Moreover, the photoluminescence at 298 and 77 K and anion exchange properties of1were also discussed.
