Abstract
We report the hierarchical supramolecular organization of metallosupramolecular homochiral complexes 1-?-(S,S,S,S)-M2+/1- increment -(R,R,R,R)-M2+ and 2- ?-(S,S,S,S)-M2+/2- increment - (R,R,R,R)-M2+ of M2+ = Co2+, Fe2+, Zn2+ metal ions with chiral pseudo-terpyridine-type ligands: 1-(S,S) or 1-(R,R) = 2,6-bis (naphthyl ethylimine)pyridine and 2-(S,S) or 2-(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 of 1- ?- (S,S,S,S)-M2+ or 1- increment - (R,R,R,R)-M2+ complexes, absolute configurations { increment (or P), ? (or M)} were confirmed by refinement of the Flack parameter x: -0.007 <= x <= 0.11 for the single crystals of 1-?-(S,S,S,S)-M2+/1- increment - (R,R,R,R)-M2+, 2- ?- (S,S,S,S)-Fe2+, and 2- increment - (R,R,R,R)-Co2+.
