Abstract

The diiridium complexes of lithium-ion endohedral fullerene Li⁺@C₆₀ were synthesised in high yields. X-ray crystallography revealed the η²:η²-coordination of Li⁺@C₆₀ and the disorder of the Li⁺ ion over two sites close to the coordinated carbons. ¹³C NMR study suggested the presence of dynamic behaviour via haptotropic rearrangements. UV/Vis and CV characteristics were also investigated experimentally and theoretically.
