Cluster chemistry refers to a field of study in chemistry that involves the synthesis and characterization of molecules comprising a group of atoms interconnected in a three-dimensional framework. Synonyms for cluster chemistry include nanocluster chemistry, molecular cluster chemistry, and metal cluster chemistry. The study of cluster chemistry allows for the understanding of the unique properties of clusters and their potential applications in various fields. Nanocluster chemistry specifically focuses on clusters on a nanoscale, while molecular cluster chemistry studies the properties of clusters made of small organic or inorganic molecules. Metal cluster chemistry is another branch that deals with the synthesis and study of clusters containing metal atoms, which have diverse applications in catalysis, materials, and biomedicine.
