文摘

A novel inorganic-organic hybrid polyoxotungstate H4[Ni(en)2]2[Ni(en)(dap)]2[Ni(dap)2]2[Ni4(en2)(PW9O34)2]-{[Ni(H2O)5]2[Ni4(en)2(PW9O34)2]}·12H2O (1, en = ethylenediamine, dap = 1,2-diaminopropane) has been successfully synthesized under hydrothermal conditions and structurally characterized by single-crystal X-ray diffraction, powder X-ray diffraction, infrared spectroscopy, elemental analysis and thermogravimetric analysis, respectively. Single-crystal structure analysis reveals that 1 exhibits a 2-D network structure based on two kinds of tetra-Ni-substituted sandwich-type Keggin polyoxoanions linked by different types of Ni-organoamine complexes.
