Under the guidance of anion templates VO and SO, the novelty of cluster assembly can be increased by using different carboxylate ligands. Herein, the synthesis, crystal structure and electrochemical properties of three anion-templated silver thiolated clusters are reported, namely VO@Ag(PrS)(CFCO)(DMF) (1), VO@Ag(PrS)(CFCO)(PhCO)(DMF) (2), and [SO@Ag(PrS)(PTA)(HPTA)] (3, HPTA = phthalic acid). Single-crystal X-ray diffraction analysis showed that 1 and 2 are discrete clusters VO@Ag. The addition of PhCOH in the second step of 1 leads to obtaining 2 with different organic shells. If the addition of HPTA is made, 3 with a three-dimensional (3D) structure containing the SO template can be obtained. Both VO and SO templates were generated under solvothermal conditions. This work is the first where heterogeneous silver clusters containing the VO anion template protected by an isopropyl thiolate ligand and a Ag cluster with a 3D structure are obtained. The assembly process influenced by carboxylic acid deserves to be continuously explored in the future.
在阴离子模板VO和SO的引导下，通过使用不同的羧酸配体可以增加簇组装的新颖性。本文报道了三种阴离子模板化的硫醇银簇合物的合成、晶体结构和电化学性质，即VO@Ag(PrS)(CFCO)(DMF) (1)、VO@Ag(PrS)(CFCO)(PhCO)(DMF) (2)和[SO@Ag(PrS)(PTA)(HPTA)] (3，HPTA = 邻苯二甲酸)。单晶X射线衍射分析表明，1和2是离散的簇合物VO@Ag。在1的第二步中加入PhCOH会得到具有不同有机壳层的2。如果加入HPTA，则可以得到含有SO模板的三维(3D)结构的3。VO和SO模板都是在溶剂热条件下生成的。这项工作首次获得了由异丙基硫醇盐配体保护的含VO阴离子模板的异质银簇以及具有3D结构的银簇。未来值得继续探索受羧酸影响的组装过程。
