Cluster chemistry is one of the most interesting and active fields in current chemistry. It was first proposed by Frank Albert Cotton in 1966 to study life sciences , material science, Organometallic chemistry And other fields are of great significance. Lu Jiaxi translated clusters into "atomic clusters" and cluster compound into“ Cluster compound ”And the transition metal cluster is translated as a transition metal cluster. There are many definitions of atomic cluster. The more comprehensive definition is proposed by Xu Guangxian, Jiang Yuansheng and others:
The structural unit formed by connecting the peripheral atoms or groups with the polyhedron or cage formed by direct bonding of three or more atoms as the core is called atomic cluster.
