“Second Organized Structures” of Nanoscale Inorganic Polyoxomolybdate Compounds

Growth of polyoxomolybdate (POM) clusters and the main role of pentagonal {(Mo)Mo5}-type building blocks in the construction principle for nanoscale inorganic polyoxomolybdate compounds were introduced. The peculiar self-assembly of the nanoscale inorganic ions in aqueous solutions was reviewed. The concepts of “second organized structures” of nanoscale inorganic molybdenum compounds and the mixtures of POMs/surfactants were proposed.
