Abstract

Abstract: We report the hierarchical supramolecular organization of metallosupramolecular homochiral complexes1 ‐Λ‐(S, S, S, S)‐M 2+ /1 ‐∆‐(R, R, R, R)‐M 2+ and2 ‐ Λ‐(S, S, S, S)‐M 2+ /2 ‐∆‐ (R, R, R, R)‐M 2+ of M 2+ = Co 2+, Fe 2+, Zn 2+ metal ions with chiral pseudo‐terpyridine‐type ligands:1‐ (S, S) or1‐ (R, R) = 2, 6‐ bis (naphthyl ethylimine)pyridine and2‐ (S, S) or2‐ (R, R) = 2, 6‐ bis (phenyl‐ethylimine)pyridine. Circular dichroism measurements in solution were used to confirm the enantiomeric nature of all twelve complexes. For crystal structures of1 ‐ Λ‐ (S, S, S, S)‐M 2+ or1 ‐∆‐ (R, R, R, R)‐M 2+ complexes, absolute configurations {∆ (or P), Λ (or M)} were confirmed by refinement of the Flack parameter x : −0.007 ≤ x ≤ 0.11 for the single crystals of1 ‐Λ‐(S, S, S, S)‐M 2+ /1 ‐∆‐ (R, R, R, R)‐M 2+, 2 ‐ Λ‐ (S, S, S, S)‐Fe 2+, and2 ‐∆‐ (R, R, R, R)‐Co 2+ .
