摘要: 采用水热法合成两个新的含铜杂多钨酸盐[Cu(en)2]6[Cu4(SiW9O34)2]?7H2O(en=乙二胺) (1)和[Cu(en)2H2O]2[Cu(en)2]4[CuSiW11O39]2?7H2O (2). 化合物1是由过渡金属配位阳离子连接的夹心型多金属氧酸盐构建成的无机-有机超分子化合物. 化合物2是具有空穴的二维(4,4)网状结构以平行交错的排列方式形成的一个3D超分子化合物, 这种在一个单胞里含有双Keggin多酸的结构目前报道的比较少. 本文通过单晶X-射线衍射、元素分析、固态电子光谱、红外光谱、热重分析对化合物1和2的结构和性质进行了测试和表征.

Abstract: Two new multi-copper-containing polyoxotungstate [Cu(en)2]6[Cu4(SiW9O34)2] 7H2O (1) and [Cu(en)2H2O]2[Cu(en)2]4[CuSiW11O39]2 7H2O (2) have been hydrothermally synthesized. The diffraction analysis reveals that the compound 1 represents the organic-inorganic hybrid based on the sandwish-type polyoxometalates linked by transition-metal coordination cations. The framework of 2 is a two-dimensional net-texture structure with vacancies in it, and the 2D layers are arranged in a parallelstaggering fashion to form a 3D supermolecules framework. It represents a 3D organic–inorganic hybrid based on the bimolecular Keggin polyoxometalates.
