From 1D to 3D Single-Crystal-to-Single-Crystal Structural Transformations Based on Linear Polyanion [Mn4(H2O)18WZnMn2(H2O)2(ZnW9O34)2]4–

A 1D anionic polyoxometalate, [Mn4(H2O)18WZnMn2(H2O)2(ZnW9O34)2]4–, undergoes 1D to 3D single-crystal-to-single-crystal structural transformations that are induced by transition-metal cations (Co2+ and Cu2+) and solvent molecules. These solid materials present interesting catalytic activity for the oxidative aromatization of Hantzsch 1,4-dihydropyridines that is dependent on the inserted heterogeneous metal cations.

一种一维阴离子型多金属氧酸盐（1D anionic polyoxometalate），其化学式为[Mn4(H2O)18WZnMn2(H2O)2(ZnW9O34)2]4–，可发生由过渡金属阳离子（transition-metal cations，Co²+与Cu²+）及溶剂分子诱导的一维至三维单晶到单晶（single-crystal-to-single-crystal）结构转变。该类固态材料对汉奇1,4-二氢吡啶（Hantzsch 1,4-二氢吡啶）的氧化芳构化反应展现出优异的催化活性，且其催化性能随嵌入的异质金属阳离子的差异而发生变化。
