| 摘要: 通过使用联咪唑及其衍生物2种有机配体在水热条件下合成了2个多酸基化合物[Ag4(biz)4][H2P2Mo5O23]·2H2O(1)和[Ag4(bbiz)4][HPW10ⅥW2ⅤO40](2)(biz=2,2-联咪唑,bbiz=5-丁基-2,2-联咪唑),并通过单晶X-射线衍射、元素分析和红外光谱对其进行了表征。 化合物1包含双核银簇[Ag2(biz)2]2+,[P2Mo5O23]6-多阴离子通过提供端基氧原子连接相邻双核银簇而构筑了一维链结构。在化合物2中,每个Keggin型阴离子提供4个桥氧原子来连接4个双核银簇[Ag2(bbiz)2]2+,从而构筑一个二维的层结构。此外,对标题化合物的电化学、光催化以及荧光性能也进行了研究。 | |

| Abstract: Through using two kinds of ligands (biimidazole and its derivative), two polyoxometalate-based compounds, [Ag4(biz)4][H2P2Mo5O23]·2H2O (1) and [Ag4(bbiz)4][HPW10ⅥW2ⅤO40] (2) (biz=2,2-biimidazole, bbiz=5-butyl-2,2-biimidazole), have been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction, elemental analyses and IR spectra. Compound 1 contains bi-nuclear [Ag2(biz)2]2+ clusters, which are linked by [P2Mo5O23]6- anions through terminal O atoms to construct a 1D chain. In compound 2, each Keggin anion offers four bridging O atoms to link four bi-nuclear [Ag2(bbiz)2]2+ clusters and a 2D layer of 2 is constructed. Additionally, the electrochemical, photocatalytic and fluorescent properties of the title compounds have been studied. CCDC: 1027614, 1; 1027615, 2. | |
