Inserting -(CH₂)_<i>n</i>- (<i>n</i> = 2, 3, 4) Spacers into the Reactant Mercapto-methyltetrazole Ligand for Tuning the Multinuclear Ag^I Clusters in Keggin-Based Compounds

Four SiMo₁₂O₄₀^4– (SiMo₁₂)-based compounds, namely, [Ag₆Cl₂(mmt)₄(H₄SiMo₁₂O₄₀)­(H₂O)₂] (<b>1</b>), [Ag₄(bmte)₂(H₂O)₂(SiMo₁₂O₄₀)] (<b>2</b>), [Ag₄(bmtr)₂(H₂O)₂(SiMo₁₂O₄₀)] (<b>3</b>), and [Ag₄(bmtb)₃(SiMo₁₂O₄₀)] (<b>4</b>) (mmt = 1-methyl-5-mercapto-1,2,3,4-tetrazole, bmte = 1,2-bis­(1-methyl-5-mercapto-1,2,3,4-tetrazole)­ethane, bmtr = 1,3-bis­(1-methyl-5-mercapto-1,2,3,4-tetrazole)­propane, bmtb = 1,4-bis­(1-methyl-5-mercapto-1,2,3,4-tetrazole)­butane), have been synthesized under hydrothermal conditions. Single crystal X-ray diffraction analyses reveal that insertion of -(CH₂)_<i>n</i>- spacers into the reactant mmt ligand plays important roles in constructing multinuclear Ag^I clusters in the title compounds and tuning the formation of different multinuclear Ag^I clusters. In compound <b>1</b>, the mmt ligands link Ag^I ions forming a three-dimensional non-multinuclear self-penetrating framework with large dimension channels occupied by SiMo₁₂ polyanions. In <b>2</b>, a tetranuclear [Ag₄(bmte)₂(H₂O)₂]⁴⁺ and SiMo₁₂ anions arrange alternately forming a one-dimensional (1D) chain. The structure of compound <b>3</b> is similar to that of <b>2</b>, except for different coordination modes of Ag^I ions in tetranuclear clusters and SiMo₁₂ polyanions owing to the longer -(CH₂)₃- alkyl skeleton of bmtr ligand. Compound <b>4</b> exhibits a two-dimensional grid layer formed by a 1D Ag^I “ribbon” based on binuclear Ag^I clusters and bridging bmtb ligands with the longest -(CH₂)₄- alkyl skeleton. The SiMo₁₂ polyanions as tetradentate inorganic linkages reside in the grids. The influences of -(CH₂)_<i>n</i>- spacers on forming and tuning different multinuclear Ag^I clusters have been discussed. Furthermore, the photochemical catalysis and electrochemical properties of the title compounds have been studied

An Effective Strategy To Construct Novel Polyoxometalate-Based Hybrids by Deliberately Controlling Organic Ligand Transformation <i>In Situ</i>

Deliberately controlling organic ligand transformation <i>in situ</i> has remained a challenge for the construction of polyoxometalate (POM)-based inorganic–organic hybrids. In this work, four POM-based hybrids assembled from an <i>in situ</i> bifurcating organic ligand[Cu₂(DIBA)₄]­(H₃PMo₁₂O₄₀)·6H₂O (<b>1</b>), [Cu₂(DIBA)₄]­(H₄SiW₁₂O₄₀)·6H₂O (<b>2</b>), [Ag­(HDIBA)₂]­(H₂PMo₁₂O₄₀)·2H₂O (<b>3</b>), [Ag₃(HDIBA)₂(H₂O)]­[(P₂W₁₈O₆₂)_1/2]·4H₂O (<b>4</b>) (DIBAH = 3,5-di­(1H-imidazol-1-yl) benzoic acid)have been designed and obtained under hydrothermal conditions. Compounds <b>1</b> and <b>2</b> are isostructural, displaying a three-dimensional (3D) 2-fold interpenetrating framework with two types of channels, and the bigger channels are occupied by Keggin polyoxoanions and crystallization water molecules, but only crystallization water molecules in the smaller ones. Compound <b>3</b> displays a 3D supramolecular structure constructed from {Ag­(HDIBA)₂} segments and PMo₁₂O₄₀^3– polyoxoanions through hydrogen bonding interactions. Compound <b>4</b> shows a 3D 2-fold interpenetrating framework based on (3, 3, 4)-connected network, which is constructed from {Ag₃(HDIBA)₂}_<i>n</i> chains and P₂W₁₈O₆₂^6– polyoxoanions as linkers. The DIBAH ligand was generated <i>in situ</i> from 3,5-di­(1H-imidazol-1-yl)­benzonitrile by deliberate design, which illustrates that the strategy to construct novel POM-based hybrids by controlling ligand transformation <i>in situ</i> is rational and feasible. In addition, the effects of the central metal and POMs on the structures of the target compounds were discussed.
