This paper is based upon the 14n Rule for transition metal carbonyl clusters and the for 4n rule for borane clusters. It reveals that the when the shielding 10n electrons are removed from the 14n based cluster what remains is a cluster that obeys the 4n rule. For instance it shows that Os₅(CO)₁₆ (14n+2) cluster of 72 valence electrons corresponds to B₅H₅^2- (4n+2) of 22 electron cluster, and Rh₆(CO)₁₆ (14n+2) corresponds to B₆H₆^2- cluster(4n+2) of 26 electrons. It is also shows that some of the giant clusters are equivalent to simple borane clusters when the shielding electrons are removed. The borane clusters so derived can readily be categorized into series which correspond to those of the carbonyl clusters. The isolobal concept has also been found to conform to cluster series.
