报道了在pH 2下纳米级{P4 W52 O 178}24-簇经pH 2-3下的{P3 W39 O 134}19-簇组装/分解为pH 3-5下的{P4 W 44 O 152}20-簇，最终在pH 6下得到{P2 W19 O 69（OH 2）}14-簇。这一过程可以在固态晶体学和溶液中使用动态光散射研究来追踪。
The pH-controlled assembly/disassembly of a nanoscale {P4W52O178}24- cluster at pH 2 to a {P4W44O152}20- cluster at pH 3-5 via a {P3W39O134}19- cluster species at pH 2-3 to finally give {P2W19O69(OH2)}14- at pH 6 is reported. This process can be traced in the solid state crystallographically and in solution using dynamic light scattering studies.
