摘　　要：以Keggin型多酸阴离子作为无机构筑单元,三氮唑作为有机构筑单元,于水热条件下,合成了一种二维配位化合物.该化合物分子式为C8H12Ag4Mo12N12O44V.利用元素分析、单晶X-射线衍射以及红外光谱对该多酸化合物进行了表征.该晶体属于单斜晶系,P21/n空间群.化合物的晶胞参数为a=10.665(5),A,b=20.761(9),A,c=11.518(5),A,α=90°,β=95.259°,γ=90°,V=2539.4(19)A^3,Z=4,ωR1=0.0301,ωR2=0.3036.在该化合物中,Keggin型阴离子[VMo12O40]3-和配体之间通过银离子相连,形成了化合物的1D链状结构.一维链之间通过与金属银配位,形成格子状2D层状结构.A two-dimensional coordination compound was synthesized by using Keggin-type polyoxometalates anion as the inorganic building block and triazole as the organic building unit under hydrothermal conditions.The compound has the formula C8H12Ag4Mo12N12O44V.The compound was characterized by single crystal X-ray diffraction,elemental analysis and infrared spectroscopy.Analysis shows that the compound belongs to the monoclinic system,P 21/n space group.The unit cell parameters of the compound are a=10.665(5),A,b=20.761(9),A,c=11.518(5),A,α=90°,β=95.259°,γ=90°,V=2539.4(19)A^3,Z=4,ωR 1=0.0301,ωR 2=0.3036.In this compound,a Keggin-type anion[VMo12O40]3-and a ligand are connected by a silver ion to form a 1D chain structure of the compound.The one-dimensional chains are coordinated with metallic silver to form a lattice-like 2D layered structure.
