在水热条件下合成了三种基于Keggin型多金属氧酸盐（POM）和NiII - 双（三唑）配合物的无机 - 有机杂化化合物，即[Ni₂(L₁)₄(SiW₁₂O₄₀)]·H₂O（1）、[Ni₂(H₂O)₄(L₂)₄(HL₂)₂][PMo₁₂O₄₀]₂·2H₂O（2）和[Ni₃(L₁)₅][PMo₁₂O₄₀]₂·14H₂O（3）（L₁ = 1,4 - 双（1,2,4 - 三唑 - 1 - 基）丁烷，L₂ = 1,6 - 双（1,2,4 - 三唑 - 1 - 基）己烷），并通过单晶X射线衍射分析、元素分析、红外光谱和热重（TG）分析对其结构进行了表征。化合物1呈现出具有六边形通道的（6,6）三维（3D）Ni - L₁框架，其中[SiW₁₂O₄₀]⁴⁻阴离子作为四齿连接体被容纳其中。在化合物2中，Ni - L₂结构单元呈现出一个由[PMo₁₂O₄₀]³⁻（PMo₁₂）阴离子为模板的三维超分子网络。在化合物3中，Ni - L₁结构单元是一个二维（2D）层，它通过PMo₁₂a阴离子连接构建成一个三维框架。三维框架相互穿插形成一个二重穿插结构，该结构……
Three inorganic–organic hybrid compounds based on Keggin-type polyoxometalate (POM) and NiII-bis(triazole) complexes, namely, [Ni2(L1)4(SiW12O40)]·H2O (1), [Ni2(H2O)4(L2)4(HL2)2][PMo12O40]2·2H2O (2), and [Ni3(L1)5][PMo12O40]2·14H2O (3) (L1 = 1,4-bis(1,2,4-triazol-1-yl)butane, L2 = 1,6-bis(1,2,4-triazol-1-yl)hexane), have been obtained under hydrothermal conditions and structurally characterized by single-crystal X-ray diffraction analyses, elemental analyses, IR spectra, and thermogravimetric (TG) analyses. Compound 1 exhibits a (66) three-dimensional (3D) Ni-L1 framework with hexagonal channels, in which [SiW12O40]4– anions have been accommodated as tetradentate linkages. In compound 2, the Ni-L2 motif exhibits a 3D supramolecular network templated by [PMo12O40]3– (PMo12) anions. In compound 3, the Ni-L1 motif is a two-dimensional (2D) layer, which is linked by PMo12a anions to construct a 3D framework. The 3D frameworks interpenetrate with each other to form a 2-fold interpenetrating structure, which ex...
