Polyoxometalate cluster anions (POMs) control formation and morphology, and serve as protecting ligands, for structurally and compositionally diverse nanostructures. Utilizing new experimental approaches and gradual understanding of the underlying chemical processes, a great advancement is recorded in the self-assembly of inorganic and metal–organic compounds at a very fast pace over the last decades. Exploitation of unveiled information originating from initial experimental observations has sparked the development of new families of compounds with unique structural characteristics and functionalities. The first part of this research article summarizes the one pot-synthetic procedure of 3d transition metal incorporated Keggin hetero polyacid using basic chemicals without using any other derived POM as starting material. In the second part of the script, we represent use of POMs as protecting ligands for stabilizing metal nanoparticles, as well as their use as templates for the preparation of new inorganic materials. Not only that, new information concerning the structure of POM-protected metal nanoparticles is systematically developed. This detailed information is obtained by the combined use of scanning and transmission electron microscopy (SEM &TEM), FTIR spectroscopy along with thermogravimetric analysis which provides a new perspective on the formation and structure of POM-decorated nanoparticles. The purpose of this research article is not the exhaustive discussion of the broad field of inorganic and metal–organic chemical systems, but to focus on a novel representative example which demonstrates the implementation of new synthetic approach and design
