【摘要】 采用水热方法合成2个新的含铜杂多钨酸盐[Cu(en)2(H2O)2][Cu(en)2]4[Cu(en)2(H2O)].[Cu4(H2O)2(SiW9O34)2].7H2O(en=乙二胺)(1)和[Cu(en)2(H2O)]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成的无机-有机超分子化合物.化合物2是由具有空穴的二维(4,4)网状结构以平行交错的方式排列形成的3D超分子化合物,通过单晶X射线衍射、元素分析、固态电子光谱、红外光谱、热重分析等对化合物1和2的结构和性质进行了测试和表征.更多还原

【Abstract】 Two new multi-copper-containing polyoxotungstates [Cu(en)2(H2O)2][Cu(en)2]4[Cu(en)2(H2O)][Cu4(H2O)2(SiW9O34)2]·7H2O(1) and [Cu(en)2(H2O)]2[Cu(en)2]4[CuSiW11O39]2·7H2O(2) were hydrothermally synthesized.The diffraction analysis reveals that compound 1 represents the organic-inorganic hybrid based on the sandwich-type polyoxometalates linked by transition-metal coordination cations.The framework of 2 has a two-dimensional net-texture structure with vacancies in it,and the 2D layers are arranged in a parallel-staggering fashion to form a 3D supermolecules framework.It represents a 3D organic-inorganic hybrid based on the bimolecular Keggin polyoxometalates.更多还原
