Synthesis and Crystal Structure of Coordination Polymer Based on Isonicotinic Acid,Ag(I) and Keggin-Type Polyoxometalate

Ren Yan

Abstract

One Keggin-based complex,[Ag12(L)8(H2O)5](SiW12O40)·6H2O(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,β=103.794(2)°,V=5.425 9(13) nm3,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.CCDC: 820578.
