摘　　要：A novel organic-inorganic hybrid, Na2（Hmorph）2[MosO26]·2H2O （1, Hmorph = morpholine）, has been synthesized by convenient aqueous solution method and structurally characterized by single-crystal X-ray diffraction, IR, UV/Vis spectrum, elemental analysis and thermogravimetric analysis （TGA）. Single-crystal X-ray analysis reveals that the title compound crystallizes in the monoclinic system, space group P21/c with a = 8.0194（4）, b = 16.1398（8）, c = 12.5893（6） A, fl = 92.824（4）°, V = 1627.47（14） A3, Mr = 1439.78, Z = 2, Dc = 2.938 g/cm3, p = 3.116 mm-1, F（000） = 1364, the final R = 0.0250, wR = 0.0628 and S = 1.027 for 3209 observed reflections with I 〉 2σ（/）. In compound 1, the polyanions are stacked through electrostatic interactions, coordination of Na＋ ions and hydrogen bonds to form a novel 3-D extended supramolecular ＂host＂ network with 1-D channels encapsulating organic ＂guests＂.A novel organic-inorganic hybrid, Na2（Hmorph）2[MosO26]·2H2O （1, Hmorph = morpholine）, has been synthesized by convenient aqueous solution method and structurally characterized by single-crystal X-ray diffraction, IR, UV/Vis spectrum, elemental analysis and thermogravimetric analysis （TGA）.
