| 摘 要： | A POMs-based 3D zeolike ionic crystal 1, {Co（dpdo）2（CH3CN）（H2O）2]2（SiMo12O40）- （HEO）2}n （dpdo = 4,4＇-bipyridine-N,N＇-dioxide）, was constructed via self-assembly by embedding Keggintype SiMo12O40]^4- polyanions within the intercrystalline voids as pillars and structurally characterized. The crystal structure was determined by single-crystal X-ray diffraction. The crystal is of triclinic, space group P1 with a = 11.430（3）, b = 12.242（3）, c = 14.279（3）A, α = 106.196（4）,β = 94.316（4）, γ = 98.294（3）°, V = 1884.5（7）A^3 Z = 1, C44H50N10O54CoEMo12Si, Mr = 2880.17, Dc = 2.538 g/cm^3, p = 2.484 mm^-1,F（000） = 1388, the final R = 0.0383 and wR = 0.1096 for 7753 observed reflections with I 〉 2σ（I）. Flack factor is 0.22（3）. Compound 1 is a pillar-layered framework with the SiMo12O40]^4- anions linearly located on the square voids between the 2D bilayers which are formed by the dpdo ligands and cobalt（II） ions.

| Abstract: | A POMs-based 3D zeolike ionic crystal 1, { Co(dpdo)2(H2O)2(CH3CN)]2(SiMo12O40)-(H2O)2}n (dpdo=4,4'-bipyridine-N,N'-dioxide), was constructed via self-assembly by embedding Keggin-type SiMo12O40]4- polyanions within the intercrystalline voids as pillars and structurally characterized. The crystal structure was determined by single-crystal X-ray diffraction. The crystal is of triclinic, space group P1 with a=11.430(3), b=12.242(3), c=14.279(3)A, α=106.196(4), β=94.316(4), γ=98.294(3)°, V=1884.5(7) A3, Z=1, C44H50N10O54Co2Mo12Si, Mr=2880.17, Dc=2.538 g/cm3,μ=2.484 mm-1, F(000)=1388, the final R=0.0383 and wR=0.1096 for 7753 observed reflections with I > 20(I). Flack factor is 0.22(3). Compound 1 is a pillar-layered framework with the SiMo12O40.]4- anions linearly located on the square voids between the 2D bilayers which are formed by the dpdo ligands and cobalt(H) ions. |
