for binary co‐assembly of complexes of different metals through quasiracemate crystallization, the hexadentate ligand 1 comprised of the chiral bipyrrolidine core and two bipyridine peripheral arms is introduced. Ligand 1 was found to bind in a fully diastereoselective and uniform mode around ZnII, FeII and CdII giving coordinatively inert octahedral “chiral‐at‐metal” complexes with the Δ4Λ2/Λ4Δ2 wrapping
