Abstract Great bowls of fire : The rotation of the cyclopentadienyl (Cp) ring is restricted in two concave‐bound monoalkyl‐substituted [CpFe(η 6 ‐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 )‐ s BuCpFe complex showed magnetic and optical desymmetrization of the sumanene ligand, which is the first example of a chiral complex of a π‐bowl ligand.
