A new three-dimensional interpenetrated Cd(II)-organic framework based on 3,3'-azodibenzoic acid [3,3'-(diazenediyl)dibenzoic acid, H2azdc] and the auxiliary flexible ligand 1,4-bis(1H-imidazol-1-yl)butane (bimb), namely poly[[bis[μ2-1,4-bis(1H-imidazol-1-yl)butane-κ(2)N(3):N(3')][μ2-3,3'-(diazenediyl)dibenzoato-κ(2)O:O']cadmium(II)] monohydrate], {[Cd(C14H8N2O4)(C10H14N2)2]·H2O}n, (1), was obtained by a typical solution reaction in mixed solvents (water and N,N'-dimethylformamide). Each Cd(II) centre is six-coordinated by two O atoms of bis-monodentate bridging carboxylate groups from two azdc(2-) ligands and by four N atoms from four bimb ligands, forming an octahedral coordination environment. The Cd(II) ions are connected by the bimb ligands, resulting in two-dimensional (4,4) layers, which are further pillared by the azdc(2-) ligands, affording a threefold interpenetrated three-dimensional α-Po topological framework with the Schläfli symbol 4(12)6(3). The thermal stability and solid-state fluorescence properties of (1) have been investigated.
基于3,3'-偶氮二苯甲酸[3,3'-(重氮二亚基)二苯甲酸，H2azdc]和辅助柔性配体1,4-双(1H-咪唑-1-基)丁烷(bimb)合成了一种新型三维互穿的Cd(II)有机骨架，即聚[[双[μ2-1,4-双(1H-咪唑-1-基)丁烷-κ(2)N(3):N(3')][μ2-3,3'-(重氮二亚基)二苯甲酸根-κ(2)O:O']镉(II)]一水合物]，{[Cd(C14H8N2O4)(C10H14N2)2]·H2O}n，(1)，通过在混合溶剂(水和N,N'-二甲基甲酰胺)中的典型溶液反应得到。每个Cd(II)中心由来自两个azdc(2-)配体的双单齿桥连羧酸根基团的两个O原子和来自四个bimb配体的四个N原子六配位，形成八面体配位环境。Cd(II)离子通过bimb配体连接，形成二维(4,4)层，这些层进一步由azdc(2-)配体支撑，得到具有Schläfli符号4(12)6(3)的三重互穿三维α-Po拓扑骨架。对(1)的热稳定性和固态荧光性质进行了研究。
