Two chiral supramolecules with enantiomeric three-dimensional porous host frameworks, (Δ){[FeII(phen)3][FeIIINa(C2O4)3]}n (1) and (Λ){[FeII(phen)3][FeIIINa(C2O4)3]}n (2) (phen = 1,10-phenanthroline), have been synthesized, and their crystal structures have been determined. The structural analysis shows that compounds 1 and 2 are a pair of enantiomers, both consisting of a three-dimensional porous skeleton formed by (Δ)/(Λ){[FeIIINa(C2O4)3]2-}n and guest (Δ)/(Λ)[Fe(phen)3]2+ units. The circular dichroism spectrum measurements confirmed the optical activity and the enantiomeric nature of complexes 1 and 2.
