一类新的配位聚合物[{Cd（d-ca）（bte）}·H2O]n（1，d-H2 ca = d-樟脑酸，bte = 1，2-双（1，2，4-三唑-1-基）乙烷），[Cd 4（d-ca）4（btp）2（H2O）4]n（2，btp = 1，3-双（1，2，4-三唑-1-基）丙烷），[{Cd（d-ca）（btb）1.5}·3 H2O]n（3，btb = 1，4-双（1，2，4-三唑-1-基）丁烷），[{Cd 4（d-ca）4（bth）4}·2 H2O]n（4，bth = 1，6-双（1，2，4-三唑-1-基）己烷）和[{Cd（d-Hca）2（bth）（H2O）}·H2O]n（5）的配合物，通过元素分析、IR、热重和X射线结构分析。具有不同间隔基长度的双三唑配体表现出构象的灵活性，并导致产生多样化的结构。复形1表示一个具有（4，4）拓扑的二维（2D）矩形网络。配合物2为手性三维骨架，具有（32·4）（3·84·12）（83）（4·8·10）拓扑结构。在化合物3中发现了具有一维（1D）纳米尺寸通道的2D蜂窝图案。化合物4是一个具有（4，4）拓扑结构的二维单分子层。
A new family of coordination polymers, [{Cd(d-ca)(bte)}·H2O]n (1, d-H2ca = d-camphor acid, bte = 1,2-bis(1,2,4-triazol-1-yl)ethane), [Cd4(d-ca)4(btp)2(H2O)4]n (2, btp = 1,3-bis(1,2,4-triazol-1-yl)propane), [{Cd(d-ca)(btb)1.5}·3H2O]n (3, btb = 1,4-bis(1,2,4-triazol-1-yl)butane), [{Cd4(d-ca)4(bth)4}·2H2O]n (4, bth = 1,6-bis(1,2,4-triazol-1-yl)hexane), and [{Cd(d-Hca)2(bth)(H2O)}·H2O]n (5), have been prepared under hydrothermal conditions and characterized by elemental analyses, IR, thermogravimetric and X-ray structural analyses. The bis(triazole) ligands with different spacer lengths exhibit conformational flexibility and lead to the generation of diversified architectures. Complex 1 shows a two-dimensional (2D) rectangular network with (4,4) topology. Complex 2 displays the chiral three-dimensional (3D) framework with (32·4) (3·84·12) (83) (4·8·10) topology. The 2D honeycomb motif with one-dimensional (1D) nanosized channels is found in compound 3. Compound 4 is a 2D parallelogram sheet with (4,4) topolog...
