| 摘要: 以柔性配体为原料，在水热条件下合成了1个新的三维镉配位聚合物{[Cd2L(OH)(H2O)]·2H2O}n(1)(H3L=5-4-(1H-四唑基)苯氧基-间苯二甲酸)，并对其进行了元素分析、红外、热重、荧光以及单晶X-衍射表征及研究。单晶衍射结果表明，配合物结晶于三斜晶系P1空间群。配合物中，相邻的Cd(1)和Cd(2)原子通过μ3-桥联的羟基形成1个四核镉簇单元。相邻的四核簇二级构筑单元通过5-4-(1H-四唑基)苯氧基-间苯二甲酸连接形成三维结构。配合物1的荧光测试表明该化合物是1个潜在的蓝色发光材料。 |

| Abstract: Anew complex {[Cd2L(OH)(H2O)]·2H2O}n (1)(H3L=5-(4-(1H-tetrazol-5-yl)phenoxy) isophthalic acid) with a flexible ligand has been synthesized under hydrothermal conditions，and characterized by elemental analysis, infrared spectroscopy (IR), thermogravimetry analysis (TG), fluorescent spectra, powder and single-crystal X-ray diffractions. Single crystal structural analysis reveals complex crystallizes in triclinic space group of P1. In complex, adjacent Cd(1) and Cd(2) atoms were connected by μ3-bridging hydroxide anion to form a tetranuclear Cd cluster. These tetranuclear Cd(Ⅱ) secondary building units were further interconnected by the L3- ligand to form a three-dimensional (3D) structure. The fluorescent characterization of 1 indicates that the compound s may be a candidate for blue fluorescent materials. CCDC: 919803. |
