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.
