摘　　要：选择一种半刚性的双吡啶-双酰胺配体N,N’-双(吡啶-3-基)环己烷-1,4-双酰胺(L)为含氮配体,在水热条件下进行反应自组装,得到了一个新的二维镉配合物[Cd(L)(Cl)2]n,并通过X-射线单晶衍射和元素分析的手段,对配合物的结构进行了表征.结果发现,配合物属于三斜晶系,P-1空间群,主要晶体学参数为:a=6.9937(8)A,b=9.4131(11)A,c=15.1079(18)A,α=83.977(2)°,β=87.402(2)°,γ=77.115(2)°,V=963.9(2)A3.该配合物是一个基于一维链[Cd(Cl)2]n和双核环{Cd2(L)2}的二维层状结构.性质研究表明,配合物不仅具有较好的固态荧光发射行为,而且对有机染料刚果红还表现出了一定的光催化降解作用.Selecting N,N’-bis(pyridin-3-yl)cyclohexane-1,4-dicarboxamide(L)as the N-containg ligand, a cadmium complex [Cd(L)(Cl)2]nhas been synthesized under the hydrothermal condition, the structure of which has been characterized by X-ray single crystal diffraction and elemental analysis. The complex is triclinic systemwithP-1 space group, a = 6.9937(8)A, b = 9.4131(11)A, c = 15.1079(18)A, α = 83.977(2)°, β = 87.402(2)°,γ = 77.115(2)°, V = 963.9(2)A3.The cadmium complex has a two-dimensional layered structure based on onedimensional [Cd(Cl)2]nchains and dinuclear {Cd2(L)2} loops. Meanwhile, the complex displays not only fluorescence emission behavior but also photocatalytic activity toward the degradation of organic dye.
