| 摘要: 水热条件下，合成得到了异烟酸与Ag(Ⅰ)及硅钨酸所形成的配位聚合物[Ag12(L)8(H2O)5](SiW12O40)·6H2O(1) (L=isonicotinate，异烟酸)。通过元素分析和红外光谱、紫外光谱、X-射线单晶衍射对其组成和结构进行了表征。晶体结构分析结果表明：该配合物属于单斜晶系，C2/m空间群；晶胞参数分别为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；异烟酸与Ag(Ⅰ)及硅钨酸形成具有微孔的三维结构配位聚合物，即硅钨酸离子通过静电作用连接异烟酸离子与Ag(Ⅰ)所形成的二维波浪式网格而形成三维结构。 |

| 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.
