Abstract
Under the guidance of anion templates V10O286- and SO42-, the novelty of 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 V10O28@Ag46(iPrS)28(CF3CO2)12(DMF)2 (1), V10O28@Ag46(iPrS)30(CF3CO2)8(PhCO2)2(DMF)4 (2), [SO4@Ag20(iPrS)10(PTA)3(HPTA)2]n (3, H2PTA = phthalic acid). Single-crystal X-ray diffraction analysis showed that 1 and 2 are discrete clusters V10O28@Ag46. Additional PhCO2H was added in the second step of 1 to obtain 2 with different organic shells. If the additional addition is H2PTA, 3 of the three-dimensional (3D) structure containing the SO42- template can be obtained. Both V10O286- and SO42- templates were generated in situ under solvothermal conditions. This work is the first to obtain the heterogeneous silver clusters containing V10O286- anion template protected by isopropyl thiolate ligand and Ag20 cluster with 3D structure. The assembly process influenced by carboxylic acid deserves continuous exploration in the future.
