Cluster chemistry is dominated by structural aspects. Indeed, structure and bonding are strongly related to stability and properties, and cluster structures are particularly diverse and often complex. Thus, electron-counting rules, which relate structure to electron count, have been the key to the development of cluster chemistry as a distinct area of chemistry. These rules have been set up progressively along time with the help of quantum chemistry. This article deals with the recent progress on transition metal and mixed main group/transition metal cluster chemistry arising from the contribution of modern computational theory to the rationalization of structures. This article focuses on “viable” species, i.e., molecules that are isolable under reasonable conditions and deals with the exploration of the limitations of the classical electron-counting rules as well as the establishment of new rules for new structural types with the help of quantum chemical calculations.
