“…In 1970s, the Wade-Mingos electron-counting rule was proposed and later employed in the cluster chemistry. [18,19] However, this rule of thumb cannot fully describe ligand-protected Au nanoclusters. [20] In 2008, Walter and Hä kkinen et al proposed the superatom complex (SAC) model to explain high stabilities of some spherical ligand-protected Au nanoclusters with total count of valence electrons of 2,8,18,34,58 (electronic shell closing) on basis of the jellium model.…”

A grand unified model (GUM) has been proposed recently to understand structure anatomy and evolution of liganded gold clusters. In this work, besidesthe two types of elementary blocks (triangular Au 3 (2e) and tetrahedral Au 4 (2e)), we introduce a secondary block, namely, the icosahedral Au 13 with 8e valence electrons, noted as Au 13 (8e). Using this secondary block, structural anatomy and evolution of a special group of liganded gold nanoclusters containing icosahedral Au 13 motifs can be conveniently analyzed. In addition, a new ligand-protected cluster Au 49 (PR 3 ) 10 (SR) 15 Cl 2 is predicted to exhibit high chemical and thermal stability, suggesting likelihood of its synthesis in the laboratory.

“…The Wade-Mingos rules (Wade, 1971;Mingos, 1972Mingos, , 1984Mingos, , 1991 have widely been utilized to categorize clusters. The 4n series method of categorizing clusters that has recently been developed (Kiremire, 2015a;2015b) complements the PSEPT method.…”

Metalloboranes have been categorized by using 4n series method. More than one hundred metalloboranes have been analyzed and characterized by the method. The clusters have been found to be centered within the series range S = 4n+6 to 4n-8. According to the classification, the clusters of series S= 4n+0 are mono-capped, S = 4n-2, bi-capped, S = 4n-4, tri-capped, S = 4n-6, tetra-capped and S= 4n-8, penta-capped. Whereas the known stable boranes have almost non-existent capped boranes, such clusters are prevalent within metalloborane complexes. This implies that metal fragments have the potency of stabilizing the fragile capped boranes.

“…The Wade-Mingos rules (PSEPT) have been exceedingly helpful in analyzing and categorizing clusters for several decades (Wade, 1971;Mingos, 1972;Rudolph, 1976;Welch, 2013). In an attempt to understand these rules and the pattern within clusters especially the osmium carbonyls, the 14n and 4n rules were revealed for transition and main group elements (Kiremire, 2014;Kiremire, 2015a).…”

The evolution of the use of the 14/4n series method has resulted in the discovery of skeletal numbers. The skeletal numbers have rendered the testing of the 18-and 8-electron rules much easier and faster. In the same way, they have been very useful in simplifying the categorization of clusters, the prediction of shapes, and the matching of isolobal fragments. Furthermore, the skeletal numbers have made it possible to tentatively assign ligands to individual skeletal elements in such way that the 18-or 8-electron rule is obeyed. Thus, skeletal numbers can be utilized as a simple guide in analyzing and understanding clusters.
