Abstract
Copper-cluster sites in biology exhibit unique spectroscopic features reflecting exchange coupling between oxidized Cu’s and e− delocalization in mixed valent sites. These novel electronic structures play critical roles in O2 binding and activation for electrophilic aromatic attack and H-atom abstraction, the 4e−/4H+ reduction of O2 to H2O, and in the 2e−/2H+ reduction of N2O. These electronic structure/reactivity correlations are summarized below.Keywords
