Summary: The crystal structure of rigid, hollow, racemic binaphthyl poly(ether ketone) macrocycles has been elucidated by single crystal X‐ray analysis. Multitudinal interactions were identified within the chiral space group P 2 1 2 1 2 1 . The structural analysis revealed that this macrocyclic compound contains an elliptic chiral cavity with a size of 9.80 × 5.18 Å, which is similar to that of cyclodextrins. The knowledge about the interaction sites and the structure of the binaphthyl‐based macrocycle provides a unique opportunity to understand its molecular or chiral recognition properties.Space‐filling representation of the single (R)‐macrocycle.
