Great bowls of fire: The rotation of the cyclopentadienyl (Cp) ring is restricted in two concave-bound monoalkyl-substituted [CpFe(η6-sumanene)]+ “π-bowl” complexes (see picture). The asymmetric stacking of atropisomers was observed with a MeCpFe complex in the solid state and the chiral (S)-sBuCpFe complex showed magnetic and optical desymmetrization of the sumanene ligand, which is the first example of a chiral complex of a π-bowl ligand.
