摘要

Two new polyoxometalates containing [PW9O34](9-) (abbreviated as PW9) subunits, carboxyltin groups and transition metal ions, namely K-10[Mn-2{Sn(CH2)(2)COO}(2)[(B-alpha-PW9O34)(2)]center dot 14H(2)O (1) and Na8K2[Zn-2{Sn(CH2)(2)COO}(2)[(B-alpha-PW9O34)(2)]center dot 13H(2)O (2), were successfully assembled in aqueous solutions by a routine synthetic method, and fully characterized. They represent the first single crystal examples of open-chain carboxyethyltin group-modified Keggin sandwich-type tungstophosphates. Their important structural features are two open-chain carboxyethyltin moieties attached on the PW9 dimer, forming arm-type polyoxometalates. Furthermore, the fluorescence properties, electrocatalytic and oxidation catalytic activities were evaluated. More interestingly, the fluorescence quenching of 1/2-doped TiO2 was clearly observed, which means that the two compounds may be excellent components of photocatalytic materials.
