Abstract: The novel One-dimensional chain structure of the title cluster compound was synthesized and characterized by elemental analysis, IR spectra, TGA and X-ray single-crystal diffraction. The title cluster compound crystallized in a monoclinic system with space group C2/c, a=1.2656 nm, b=2.20656(4) nm, c=2.26763(4) nm, β= 92.078°, V=6.32852(16) nm3, Z=4, Dc= 3.801 g/cm3, μ=2.271 mm-1, F(000)=6512, R1=0.0549, wR2=0.1087. The structure building block of the structure is the polyanion [SiW12O40]6- with α-Keggin structure. The clusters were linked together with one-dimensional infinite chain through [Ni(enMe)2]2+ cations. The [Ni(enMe)2(H2O)2]2+ cations and water molecules were filled in the structure. The cluster compound was expanded to three-dimensional framework by hydrogen bond interactions among molecules.
