Unprecedented Bending and Rearrangement of f-Element Sandwich Complexes Induced by Superbulky Cyclooctatetraenide Ligands
The use of the superbulky cyclooctatetraenide dianion ligand [C8H6(SiPh3)(2)](2-) (= COTBIG) in organo-f-element chemistry leads to unprecedented effects such as the formation of a significantly bent anionic Ce-III sandwich complex, a novel cerocene formed by sterically induced SiPh3 group migration, as well as the first example of a bent uranocene.
