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".
