摘　　要：The supennolecular based on sodium molybdate（Ⅵ） and sulfate, dibenzo-18-crown-6 was synthesized in acetonitrile and characterized by elemental analysis, IR,^1H NMR, single crystal X-ray diffraction, indicating that it contains [S2M018062]^4＋ and [Na（DB18Cr）（H2O）]^＋, where each sodium ion is deviated from the plane defined by the oxygen atoms in the corresponding crown ether. The compound crystallizes in the monoclinic space group C2/c with a=3.29332（10） nm, b= 1.90917（6） nm, c=2.63132（7） nm, β= 121.6630（10）°, V=14081.8（7） nm^3, Z=8, T=293（2） K, and R1（wR2）=0.0177 （0.1525）. The compound exhibits a novel organic-inorganic structure, in which the crown ether-sodium complexes are coordinated to the terminal oxygen atoms of Mo18054 and the oxygen atoms of water molecule.The supennolecular based on sodium molybdate（Ⅵ） and sulfate, dibenzo-18-crown-6 was synthesized in acetonitrile and characterized by elemental analysis, IR,^1H NMR, single crystal X-ray diffraction, indicating that it contains [S2M018062]^4＋ and [Na（DB18Cr）（H2O）]^＋, where each sodium ion is deviated from the plane defined by the oxygen atoms in the corresponding crown ether.
