Abstract

Two {Ni6} cluster-containing inorganic-organic hybrid compounds have been successfully synthesized in the presence of organic amine under hydrothermal conditions, and they were characterized by powder and single-crystal X-ray diffraction, elemental analysis, thermogravimetric analysis, and IR spectroscopy. Structural analysis indicates that [Ni0.5(H2O)3][{Ni6(μ3-OH)3en(H2O)10}(H2P2W15O56)]·10H2O (1, en = ethylenediamine) is a triangular inorganic {Ni6} cluster substituted polyoxotungstate with only one en to stabilize the {Ni6} cluster. However, [Ni(dap)2]{[Ni1.5(dap)1.5(H2O)3][Ni6(μ3-OH)3(dap)2(en)(H2O) {O2C(CH2)2CO2}0.5(CH3COO)(P2W15O56)]}·15H2O (2, dap = 1,2-diaminopropane) is a three-dimensional inorganic-organic hybrid compound linked by succinic acid. The magnetic properties of both compounds were studied. In addition, the adsorption properties of compound 2 have also been investigated.

摘要

在水热条件下，在有机胺存在的情况下成功合成了两种含{Ni6}簇的无机-有机杂化化合物，并通过粉末和单晶X射线衍射、元素分析、热重分析和红外光谱对其进行了表征。结构分析表明，[Ni0.5(H2O)3][{Ni6(μ3-OH)3en(H2O)10}(H2P2W15O56)]·10H2O（1，en = 乙二胺）是一种三角形无机{Ni6}簇取代的多金属氧酸盐，仅有一个en来稳定{Ni6}簇。然而，[Ni(dap)2]{[Ni1.5(dap)1.5(H2O)3][Ni6(μ3-OH)3(dap)2(en)(H2O){O2C(CH2)2CO2}0.5(CH3COO)(P2W15O56)]}·15H2O（2，dap = 1,2-二氨基丙烷）是一种由琥珀酸连接的三维无机-有机杂化化合物。研究了这两种化合物的磁性。此外，还研究了化合物2的吸附性能。
