One Keggin-based complex, [Ag(12)(L)(8)(H(2)O)(5)](SiW(12)O(40))center dot 6H(2)O (1) (L=isonicotinate) was synthesized under hydrothermal condition. The complex was characterized by elemental analysis, IR spectra UV spectra and X-ray single crystal diffraction. The crystal belongs to monoclinic crystal system, space group C2/m with a=1.259 5(2) nm, b=2.429 7(3) nm, c=1.825 7(3) nm, beta=103.794(2)degrees, V=5.425 9(13) nm(3), Z=2. Single crystal structural analysis reveals that the complex is a porous Keggin-based 3D coordination polymer based on the incorporation of void between 2D metal-organic networks and Keggin anion.
