| 摘 要： | A new supramolecular compound, {[Cd(L)2]2[PMo12O40NO3]·CH3CN·2H2O}n 1 (L is 1,4-bis(4-imidazolyl)-2,3-diaza-1,3-butadiene), based on Cd(II)-Schiff-base and Keggin- type [PMo12O40]3- was synthesized via self-assembly and structurally characterized by elemental analysis, infrared spectroscopy, and single-crystal X-ray diffraction analysis. The crystal is of triclinic, space group P1 with a = 12.0128(11), b = 13.6196(13), c = 13.9995(13) , α = 103.868(2), β = 95.225(2), γ = 101.024(2)°, V = 2160.0(3) 3, Z = 1, C34H39N26O45Cd2Mo12P, Mr = 2938.96, Dc = 2.259 g/cm3, μ = 2.276 mm-1, F(000) = 1400, the final R = 0.0565 and wR = 0.1613 for 4973 observed reflections with I 2σ(I). The crystal structure can be described by the packing of Keggin anionic and Metal-Schiff-base cationic layers.
