摘要: 通过水热方法制备了一个三维配位聚合物[Ni2(bte)5(γ-Mo8O26)]·5H2O(1)(bte=1,2-二(1,2,4-三氮唑-1)乙烷),并通过元素分析、热重分析、单晶X-射线衍射对其进行了表征。结构分析表明bte配体与Ni(Ⅱ)连接形成了一个独特的二维金属有机层。多酸阴离子(γ-[Mo8O26]4-)在结构中起到了两种不同的作用:(i)它作为结构导向剂嵌在二维的金属有机层中;(ii)它通过Mo-N键连接相邻的二维金属有机层构筑了一个三维框架。此外,还研究了化合物1的电化学性质和荧光性质。

Abstract: A new 3D coordination polymer [Ni2(bte)5(γ-Mo8O26)]·5H2O(1) (bte=1, 2-bis(1, 2, 4-triazol-1-y1)ethane), has been synthesized under hydrothermal conditions and characterized by elemental analyses, thermogravimetric analysis (TGA) and single crystal X-ray diffraction. The crystal structure analysis indicates that in compound 1, the bte ligands link the Ni(Ⅱ) ions and construct a unique 2D metal-organic layer. The γ-[Mo8O26]4- anions show two different functions: (i) it acts as a structural directing agent embeding in the 2D metal-organic layer; (ii) it is functionalized by the bte ligands through Mo-N bonds for bridging this 2D metal-organic layer and finally inducing a 3D framework of 1 with the Schläfli symbol of {32·44·54·62·73}{32·46·56·6}2. In addition, the electrochemical and fluorescence properties of the title compound have been studied. CCDC: 881771.
