摘要

The supermolecular 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 [S2Mo18O62]4+ and [Na(DB18C6)(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, beta=121.6630(10)degrees, V=14081.8(7) nm3, 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 Mo18O54 and the oxygen atoms of water molecule.
