| 中文摘要 | two novel dibenzo-18-crown-6 sodium isopolytungstates, [(db18c6)(ch3oh)na](2)w(6)o(19)(.)db18c6(.)h(2)o 1 and [(db18c6)(dmf)(2)na](4)w(10)o(32)(.)2dmf(.)2h(2)o 2, have been synthesized in mixed methanol and acetonitrile solvents and characterized by elemental analysis, tga, ir and single crystal x-ray diffraction. the compound 1 crystallizes in the monoclinic space group c2/c with a = 23.182(8), b = 19.527(2), c = 18.737(3) angstrom, beta = 115.15(2)degrees, v = 7678(3) angstrom(3), z = 4, and r1(wr2) = 0.0611(0.1504). the compound 2 crystallizes in the monoclinic space group p21/n with a = 16.516(2), b = 22.325(6), c = 20.425(7) angstrom, beta = 91.78(2)degrees, v = 7528(3) angstrom(3), z = 2, and r1(wr2) = 0.0397(0.0773). the compound 1 exhibits a novel organic-inorganic sandwich-type structure, in which the crown ether-sodium complexes are coordinated to the terminal oxygen atoms of w6o192-. in compound 2, all na+ ions are thoroughly enveloped into the organic moieties of crown ether and dmf molecules and are connected with the 'naked' polyanions w10o324- via the electrostatic attraction. |
