Abstract

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.
