Copper clusters built on bulky amidinate ligands: spin delocalization via superexchange rather than direct metal-metal bonding.
Entry into a new class of tetra- and dicopper clusters was assisted by a fine steric tuning of bulky amidinate ligands that provide spin-delocalizing superexchange pathways in class III mixed-valence clusters, the properties of which are best understood without invoking metal-metal bonding.
