中文摘要	three novel supramolecular assemblies constructed from polyoxometalate and crown ether building blocks, [(db18c6)na(h2o)(1.5)](2)mo6o19.ch3cn, 1, and [{na(db18c6)(h2o)(2)}(3)(h2o)(2)]xmo12o40.6dmf.ch3cn (x = p, 2, and as, 3; db18c6 = dibenzo-18-crown-6; dmf = n,n-dimethylfomamide), have been synthesized and characterized by elemental analyses, ir, uv-vis, epr, tg, and single crystal x-ray diffraction. compound 1 crystallizes in the tetragonal space group p4/mbm with a = 16.9701(6) angstrom, c = 14.2676(4) angstrom, and z = 2. compound 2 crystallizes in the hexagonal space group p6(3)/m with a = 15,7435(17) angstrom, c = 30.042(7) angstrom, gamma = 120degrees, and z = 2. compound 3 crystallizes in the hexagonal space group p6(3)/m with a = 15.6882(5) angstrom, c = 29.9778(18) angstrom, gamma = 120degrees, and z = 2. compound 1 exhibits an unusual three-dimensional network with one-dimensional sandglasslike channels based on the extensive weak forces between the oxygen atoms on the [mo6o19](2-) polyoxoanions and the ch2 groups of crown ether molecules, compounds 2 and 3 are isostructural, and both contain a novel semiopen cagelike trimeric cation [{na(db18c6)(h2o)(2)}(3)(h2o)(2)](3+). in their packing arrangement, an interesting 2-d "honeycomblike" "host" network is formed, in which the [xmo12o40](3-) (x = as and p) polyoxoanion "guests" resided.
