A POMs-based 3D zeolike ionic crystal 1,{[Co(dpdo)2(CH3CN)(H2O)2]2(SiMo12O40)-(H2O)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) ,α = 106.196(4),β = 94.316(4),γ = 98.294(3)°,V = 1884.5(7) 3,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 > 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.
